Intel's New Pentium 4 Chipsets Reviewed 125
RainDog writes "Intel has released its 845PE and GE chipsets for the Pentium 4 processor, and reviews are hitting the web. The new chipsets officially support DDR333, but are stuck with AGP 4X and ATA/100 support. What's most interesting about these new chipsets is that they're faster than VIA and SiS' latest Pentium 4 offerings, both of which support faster AGP 8X and ATA/133 graphics and disk interfaces. As if that weren't enough, Intel's new "Blue Mountain" motherboard comes on a black PCB with all sorts of multimedia ports and memory timing options. Not bad for the traditionally conservative Intel."

Improved hyperthreading support - go check out the Ars Technica [arstechnica.com] article on this. Hyperthreading can potentially really help performance, but it's being held back by (among other things) problems with cache coherency and loading.

"Cheap consumer crap" is what sells the most, and most companies do not have the resources to do work on more than a couple of chipsets at a time, so most of the R&D time is spent on implementing the new standards and getting things to work at the new frequencies that CPUs and RAM require.

How about huge L3 Cache? The problem with hyperthreading is that by definition it is going to cause a larger number of cache misses. Since you are maintaining 2 seperate contexts in one processor. In order to speed that up you are going to need more cache. Faster main ram will help, but won't solve it.
This was already mentioned, but for Hyperthreading it seems to me that it is almost required if you want to get decent performance out of more types of applications. Hyperthreading is supposed to give the largest speed up to a multi-threaded application that processes similar data.
Re:Is it me.... (Score:2)
Another level of cache in the chipset is not going to help much. Integrating fast memory into the northbridge itself is prohibitive from the cost standpoint -- who's going to pay $100 more for a northbdirge when they can get another 500MHz added to their CPU for the same price, with much more impact? Using separate, high-speed DRAM that today's graphics cards use will bring the cost increase somewhat down, but the latency improves negligibly -- most of it is wasted on CPU to northbridge communication, and inside the northbridge itself, and the faster RAM might give you 5% latency increase.
So, any additional cache would have to be hooked up to the CPU directly to possibly produce results, and that's out of chipset designer's hands.
The best solution is, probably, to increase L2 cache size, or use a better sharing mechanism during hyperthreading to prevent two threads from thrashing each other's caches.
Re:Is it me.... (Score:2)
Part of the issue was raised in a post a couple parents down, is if the CPU is starved for data, the extra clock speed won't do jack. And those that want the max performance would pay more for the fastest CPU AND get the most cache rather than trading off on cost factors.
For this very reason, I understand that one can get RISC workstations that have as much as 8MB of cache on die, on the processor card or next to the CPU somehow.
So, any additional cache would have to be hooked up to the CPU directly to possibly produce results, and that's out of chipset designer's hands.
Basically, if you want more on-die cache, that was in Xeon territory, where you pay a lot of money for a chip with the circuitry built-in, but I'm sure Xeons weren't available in 8MB L2s built-in.
Because the processor card idea seems to have been abandoned by Intel, recent iterations if Xeons max out at 512k L2. Cartridged PIII Xeons seem to be still available new with 1M and 2M iterations, with 700 and 900 MHz clocks.
Re:Is it me.... (Score:2)
But, my point is that the performance of another level of cache at the northbridge is much less than the extra 500MHz. None of the CPUs are curretly starved by the available bandwidth. Hungry, maybe, but there aren't many applications out there that even come close to requiring more than 3.2GB/s that the P4 can take in right now (4.2GB/s when we switch over to 133MHz FSB). So, 500MHz increase will matter in a large majority of applications.
Now, I agree with you (and have said so in my message) that a cache at the CPU side can make a difference. A $100 of cache with minimal latency from the CPU could be better than 500MHz.

Because the PCs would be a lot more expensive if 20 GB/s would have to provided to the CPU. First, the memory controller would have to be integrated into the CPU (which, mind you, AMD Hammer has, but not for b/w reasons, but latency.. the b/w is still the same), and would have to support 4 memory channels, increasing pin count by 200+ pins. That causes the CPU price to skyrocket. Then, the memory would have to run at DDRII-400MHz, instead of the 200 which you get from the fastest DDR available for PCs. That would increase the RAM prices dramatically. Finally, to handle those kinds of RAM speeds, the motherboards would have to grow to at least 6 layers, tripling the motherboard cost.
The question is -- who's going to do all that development work to sell it to a very small number of people who are willing to pay for that performance?

HyperThreading to me is the biggest con since MMX and AGP x (?) for 3D cards. It *requires* multithreaded applications to even work, the HyperT cpus eat more voltage and run hotter than cpus without it and as a result require different motherboard support than the slower-than 3.06GHz nonHyperT P4s. This thing won't even be as useful to a desktop user as a dual cpu Mac currently is for your average Mac user. In fact, if you need to run multithreaded applications (of which there are almost none in the standard software marketplace) you are *far* better off going dual-cpu SMP, and the performance difference would eat HyperT alive. What a con job this is turning out to be.

* Data Starved Processors - and this is all about latency
That's mostly a function of main memory. With 512K of cache, your hit rate is typically in the 95-98% range. Throwing tons of cache on the motherboard rarely helps much, since it usually only bumps your hit rate up to around 96-98%. Generally speaking, if your data set doesn't fit into 512KB of cache, it usually won't fit into any amount of cache, no matter how big. So what we really need is a type of memory that offers very low latency but is cheap enough that it can be used as main memory. Some technologies like prefetching can help hide this latency, but sooner or later, all those break down.
Ohh, and to make L3 cache really effective, it would probably have to be hanging off a backside bus of the processor anyway, not off the chipset. I know that Intel talked about doing this with their current line of Xeons, but I don't know what ever came of those plans.
# Improved hyperthreading support
Hyperthreading performance is about 49.5% CPU, 49.5% software, and about 1% chipset. There is virtually nothing that can be done on the chipset to specifically improve hyperthreading performance. All the chipset manufacturers could do here are fairly generalized improvements that would end up helping out chips both with and without hyperthreading.
where are nice stuff like block data copy between video and RAM (like the SGI chipsets for the Indy/O2 had)
Uggg.. copying data back and forth between main memory and the video controller? That's a sure way to hurt your performance! The SGI solution only made sense because it was cheaper/easier for them to have a single high-bandwidth bus with and a single chunk of a GB of memory or so. However if they could have had a GB of video memory and a GB of main memory, with each having tons of bandwidth, they would have been better off. PCs are in that situation. These days, having a video card with 10-20GB/s of memory bandwidth and 128MB+ of memory is cheap, which essentially eliminates the need to read/write between (slow) main memory.
There's really nothing wrong with AGP other than the fact that it's original design idea has become obsolete by the fact that memory is dirt-cheap now. Otherwise it offers over a GB/s of bandwidth for what amounts to essentially 1-time read/writes. After that, all the magic happens on the video card itself.
# Standard interfaces for custom silicon
Umm.. ok.. whatever. The market for this is approximately 2 people. Still, believe it or not, you're actually going to see just such a thing in about 6-months time with AMD's Hammer processors. These chips/chipsets will have Hypertransport links, which will offer a high-bandwidth connection directly to the chipset if you so desire. Of course, if you want to make use of it you're going to have to design your own motherboard from the ground up, because the market for what you're looking for is TINY, and no motherboard manufacturer is going to waste their money on such a thing.

Here's a sample for ya:
AMD AthlonXP 2000+ (180nm fab process): 70.0W Max, 62.5W typical
Intel P4 2.0GHz (180nm fab process): 75.3W TDP
AMD AthlonXP 2600+ (130nm fab process): 68.3W Max, 62.0W typical
Intel P4 2.60GHz (130nm fab process): 62.6W TDP
Long story short, these chips are all in the same basic range, all within about 10% of one another except for the old 2.0GHz (Willamette) P4s.
So, if the power used is roughly the same, than the only real differences comes down to how good your cooling system is, and this is why the P4 seems better. See, almost all P4 heatsinks are at least 70x70mm at their base, and most are around 80x80mm. By contrast, a lot of Athlon heatsinks are much smaller 60x60mm. However, if you use one of the 80x80mm heatsinks for an Athlon, guess what? The chip is nice and cool, even with a slow-spining fan that hardly makes any noise.
