VIA's New Nehemiah M10000 Processor Reviewed 265

Posted by timothy from the low-power-madness dept.
Joseph Wharton writes "Mini-ITX.com has a review of VIA's new Nehemiah M10000 EPIA-M motherboard and processor. Some of the new features include a full-speed floating-point unit (finally!), SSE instructions, 64KB of full-speed L2 cache, and (get this) a hardware-based random number generator. Also, there's IO/APIC support in these new procs, potentially paving the way for dual EPIA boards."

          Anyone considering a M10000 should read this [mini-itx.com] first. Basically, VIA released two separate boards under the M10000 name. The second of which is the only one to feature the Nehemiah core. The first series (the one from directron.com) still uses the older Ezra-T core. Right now, there's not many vendors who can reliably provide Nehemiah processors. The only places I've seen are idot.com and monarchcomputer.com.

          I suppose something running at that speed was state-of-the-art back around 2001. I have no need or plans to upgrade for at least a year, maybe longer.

      A hardware random-number generator is useful for crypto. If you've ever tried porting something like OpenSSH to a platform that didn't have decent RNG support (i.e. no /dev/random or /dev/urandom like Linux has), you'll have run into the fun and games of trying to come up with a decent random source.

      Hardware support for RNG is a "Good Thing(TM)", and doesn't necessarily have anything to do with the "Trusted Computing Platform" or whatever the DRM flavour of the day happens to be ! :-)
      • On a side note though, I've wondered why it is that CPU vendors haven't been able to integrate random number generation into the CPU itself. Intel had their RNG built into one of their chipsets (I think it was the 810 or 820?), but AFAIK their current chipsets don't support it anymore (correct me if I'm wrong). Anyways, it's always bugged me that there's not some sort of RNG instruction that fills the destination register or memory location with a randomly generated integer/floating point value.

    It's almost dead but here is the page about the CPU.. interesting. hehe

    "Nehemiah is the next generation C3 CPU, and features a number of improvements over the Ezra-T C3 used in all previous EPIAs. It has The 20.5 million transistors, and uses a 0.13 micron process. For comparison, a Barton Athlon or Northwood Pentium 4 have about 55 million transistors, and recent GPUs have over 100 million transistors.

    The Nehemiah is designed to work at clock speeds of 1GHz and beyond - the Ezra-T is designed at up to about 1GHz.

    Nehemiah has a die size of 52mm2 - the world's smallest x86 processor. It has been designed to minimize power consumption and optimise heat dissipation - VIA call this "Coolstream". Some active cooling is still required, but not very much. Let's hope for a Nehemiah Eden C3 version.

    The Nehemiah features SSE instructions instead of the 3DNow! instructions featured on previous C3s. This should bring enhanced performance in 3D applications, which are optimised for more modern SIMD instruction sets. SSE optimised image processing applications should also benefit.

    Full Speed FPU - the Nehemiah has a full speed floating point unit for the first time. The Ezra-T has a half-speed FPU. Floating point calculations are used heavily in 3D rendering, multimedia, and streaming applications.

    Enhanced 64KB Full-Speed Exclusive L2 cache with 16-way associativity. An exclusive L2 cache gives a larger effective total cache size as it doesn't replicate the contents of the L1 cache. The more cache available, the more chance there is that program loops can run in cache and not comparatively slow main memory.

    StepAhead Advanced Branch Prediction - Looks ahead and gathers the data needed to optimally run applications

    A hardware based random number generator (RNG) has been added. This creates true random numbers from the random electrical noise on the chip. This is of much use in security applications, allowing a strong cryptographic key to be generated. VIA call this the "PadLock Data Encryption Engine".

    Future Nehemiahs will feature IO/APIC support. An Advanced Programmable Interrupt Controller (APIC) provides multi-processor interrupt management - dual processor EPIA anyone?

    The Nehemiah is available in EBGA or Socket 370 packages - both are low profile and require less board real estate."

      Finally! A WinChip that doesn't insist on doing things the old-fashioned way.

      Three years go when VIA merged the Cyrix product name with the Winchip line, they touted the WinChip's lack of Out-Of-Order-Execution and use of Static Branch Prediciton as "features".

      This was puported to save power and make the die smaller. Funny to see them do a complete 360 only 3 years later, after their castrated chip has failed to attract a single Tier 1 vendor.

      The Cyrix MII sold better than the WinChip / VIA C3; at least Compaq and Emachines were selling systems based on it back in the day. It sold where the WinChip couldn't, because it actually delivered on being both reasonably powerful and dirt-cheap. The WinChip could claim to be dirt-cheap, but reasonably powerful...welll...

      So, after so long a wait, do we finally have a winner? A low power chip that can actually play a Divx movie? Perhaps they could get rid of that hardware DVD decoder too, a feature other systems havn't needed since the Celeron 400 / K6-2 450.

      Typically, you wouldn't use a HW RNG (Random Number Generator) to generate random numbers, you'd use it to generate entropy. You'd then mix it in with other sources of entropy using a cryptographically strong hash, and use that output as your random number.

      The way good OS's generate random numbers is by accumulating a pool of entropy. They typically use a wide variety of inputs and mix them together. That way, if an attacker is able to observe or predict some of the inputs, there's still some more than they can't break. Unfortunately most computers only have expernal sources of randomness; things like ethernet packet timing or keyboard/mouse movement. These things are relatively easy to observe and/or tamper with. (As an aside, does anyone know if any OS uses things like processor temperature/fan speed as entropy inputs?) The on-chip RNG is may not be a really excellent source of randomness, but it's very hard for an outside observer to monitor. (And, it's quite possible that it really is an excellent source of randomness.) Even if it is weak, it's another addition to the entropy pool, and thus strictly good.

      Actually, the analysis [cryptography.com] I've seen suggests that the HW RNG is very good. It can generate RNGs at 30-50 Mb/s, with an estimated 0.78-0.99 bits of entropy per output bit. With a built in "whitener", it can generate 4-9 Mb/s with an estimated 0.99+ bits of entropy per bit. If you use it as an entropy pool to feed a strong PRNG, which is the recommended mode of use, it should be a very effective source of cryptographically useful randomness.

    • I mean, once they have a analysis of the possible weaknesses of the HW, you have a big problem ;)

      Testing goes something like
      1) Get fscking big sample
      2) Run staistical analysis, typically frequency analysis. If no patterns show up (e.g. 60Hz from power supply) you're home free. No fancy algorithm analysis needed, not much to exploit really.

      Also, in a worst case scenario you can fall back to software. Though I suppose that a DRM system could get compromised if the "random" data aren't random though.

    Conclusion

    The Nehemiah M10000 is a very welcome speedbump to previous EPIA Ms. The full speed FPU and SSE instructions give it that extra boost needed to playback any media type we could find - without optimisations or quality tradeoffs.

    Although we have benchmarked the Nehemiah as fully as possible (and gained some useful comparisons with earlier EPIAs), it must be remembered that this is not everything that the EPIA is about. In use, all the EPIAs are nippier than their benchmarks would suggest, due to their supporting chipsets. EPIA Ms (of which the Nehemiah M10000 is of course the current ruler) are powerful multimedia playback machines. An EPIA M in a low profile case looks great next to a TV, where a regular PC or even Cube SFFPC will look out of place, overpowered and overpriced for the task. Add a PVR card and you have a perfect HTPC.

    As an inexpensive upgrade path for ageing x86 machines, EPIAs are ideal - schools, libraries and internet cafes can benefit from low noise and low power consumption machines. Under Linux, even the EPIA 5000 can perform tasks such as file serving with ease all at the cost of a SCSI card. EPIAs have accidentally gained a following in the modding community (witness the many projects on this site). Although such mods probably represent a small proportion of sales, they show the versatility that this form factor has, and the enthusiasm of its owners. No other manufacturer offers a range of mainstream low noise motherboards at this size and price with these facilities. Other manufacturers will be watching with interest.

    before everyone starts comparing this to p4 or athlon, it's not meant to compare to them. this chip is only 1 ghz, but the selling point is it's low power consumption and it doesn't run too hot (the slower cpu's use only passive cooling). So yeah, you're not going to be playing doom 3 on it, but you can do cool things like put it in your car [via.com.tw] or have a pc that is (almost) completely silent. So for around 200 you get a mobo/cpu/video card/sound card/etc... not too bad of a deal if you ask me...

    I think it is a great thing that a company has started to make low power cpus. Imagine all those P4 and AMD cpus out there that waits for Word to tell them to do something. You dont need 3ghz for that. A modern P4 or AMD processor uses about 70W of energy for nothing.

    Hey if you could reduce that to 35W you are not only geting 35W less for the cpu you are also lowering the power consumtion on the air condition. An office building that starts to take the power consumtion serius could save lots of cash on electrical bill and probably some on the environment to :)

    A hardware based random number generator (RNG) has been added. This creates true random numbers from the random electrical noise on the chip. This is of much use in security applications, allowing a strong cryptographic key to be generated. VIA call this the "PadLock Data Encryption Engine".

    VIA Engineers also note that this was previously a set of registers that they just couldn't iron the crosstalk kinks out of. As such, it was rebranded a feature in classic computer tradition.

    The Atari 800 had one in 1978. And Commodore 64 programmers were used to using some values from the sound hardware for the same purpose. It's funny how some ideas go away for a long time, only to resurface after most people have forgotten it.
    • And the Atari 800 also had the SIO (serial-input-output) port on it too: a universal connector for all peripherals outside of joysticks. They even had a hub for the SIO port as well. Its no wonder that the engineer responsible for the SIO port now works for Intel and holds co-patents for USB, an updated idea from Atari's heyday...
  • Can anybody with a clue comment on whether this latest relase would be able to run fanless (e.g. using a hustechnologies.net case), and would the linux/XFree drivers be able to support widescreen resolutions (the review at mini-itx.com says only traditional resolutions are supported, but this might be different in the linux/XFree world)?
  • I host a dozen or so websites on a little mini-ITX server I bought last fall for $200. Two of the sites have been slashdotted in that time, and the server cruised right through them maxing out at a few percent CPU consumption. (Static pages, of course!)

  • VIA's reluctance to support Linux (Score:5, Informative)

    On the Via Arena Forum for EPIA-M Linux support [viaarena.com] the outlook is bleak. Via seem reluctant to fully support Linux, in particular with the MPEG hardware and the EHCI USB. One person trying to develop a distribution for EPIA-M says:
    The EPIA-M's aren't very well supported on Linux at all. The bare minimum will work, but there is a lot of work to be done, especially on VIA's part.

    ...
    VIA should not claim that the EPIA-M is Linux compatible, unless it is actively supporting the Linux community by improving support to at least a level of being able to take advantage of most of the hardware's features. I hope VIA becomes more actively involved in the future.
    Here's the complete summary of hardware support for EPIA-M by "jonthorpe" on March 10, 2003:
    USB 2.0: I have been in contact with David Brownwell for the past two months in an attempt to resolve the issues with the VT8235's EHCI support in general. Most people will experience system hangs when they attempt to use the EHCI controller, although it is improving. VIA has apparently provided David with hardware, but with little support. As of late, the problem seems to extend beyond the VT8235's EHCI - on another VT8235 based board, it was revealed that there are IRQ/PCI issues causing any USB 2.0 card (e.g. an NEC which is usually stable) to hang.

    Audio: ALSA should work for the EPIA-Ms with their ALC650, but the OSS drivers are still a better option in my opinion. The original EPIAs will experience problems with ALSA (crackly sound on new versions of ALSA, no sound at all on previous). The OSS driver in newer kernels (e.g. 2.4.21-pre5-acX) works well with OSS playback, but there are two major problems:

    1. ESound does not work. This limits the user to only one stream to pass through the sound card. This can generate problems with applications such as web browsers which use the Flash plugin (especially if another sound application is already running - e.g. XMMS)
    2. Recording does not work whatsoever. This is a major problem that I am yet to talk to Alan about, but there is absolutely no recording with OSS drivers. ALSA drivers have more success with this, but the audio quality is poor.
    VGA: This will work nicely if you're running one of VIA's supported distribution versions. This is not good for people like myself who insist on using updated kernels to work with other features of their hardware. This limits us to using the Slim driver for the CLE266, removing MPEG2 hardware acceleration. I am developing a distribution that is to be bundled with EPIA-M systems, and even after mentioning that, sending two emails to VIA and signing up on the driver request page has proven fruitless and are completely ignored.

    I haven't tested this myself, but I believe there are problems with VIA's CLE266 drivers when it comes to virtual screens. The driver simply cannot handle them.

    NIC: This works flawlessly, with the via-rhine driver. There are no problems to report.

    FireWire: I have no idea about this one either, but I can say that the host controller is at least recognised by the Linux driver. I'd love to hear from anyone who has tested the EPIA-M's firewire on Linux.
