AMD's Athlon-64 Benchmarked With UT2003 227

Fig 1. The Athlon-64 system running SuSe 64-bit Linux and the 64-bits version of Unreal Tournament 2003.
Naturally we're intimately familiar with the workings of Unreal Tournament 2003 engine and after a quick look at the display settings, which were set at a 1024x768x32bit resolution with all other features at default, we measured a mere average 42fps and maximum fps around the 55...60fps mark. Considering the fact that this is a 2GHz Athlon-64 processor teamed up with a GeForce Ti 4600 we honestly expected a whole lot better. A 1.6GHz Pentium 4 with that very same GeForce Ti 4600 videocard would have no problems clocking in a similar score while running under Windows XP.
(pic of a white laptop with the terminal showing)
Fig 3. The Athlon-64 notebook running CyberLink's PowerDVD actually showing the first Harry Potter movie.
But there's more, we managed to take a closer look at the notebook too and quickly found out that this indeed is a proof of concept. It plays DVDs very well, mostly courtesy of the ATi M9-series graphics card, and unfortunately all our questions about whether we could do something else with it were answered with a resounding 'no'. We did however manage to find out what was inside in terms of chipset, memory and graphics card. The notebook apparently used a Via K8T400M chipset teamed up with an ATi M9-series graphics adapter and was using PC2100, DDR266, memory. The screen was a standard 14.1 inch running at a 1024x768 resolution and the DVD software they used was none other than CyberLink's PowerDVD.

Fig 3. The quad Opteron with the SuSe 64-bit Linux operating system running some sort of a database benchmark, right next to the UT2003 demo machine.
We naturally also took a closer look at the quad Opteron as that's definitely something AMD is currently pushing hard. They're putting all their weight behind the launch of their server products and have postponed the launch of the desktop version of the Opteron, the Athlon-64, back to September. The server parts, including completely pre-configured two-way Opteron systems, should be available in late April, right after the April 26th launch of the Opteron server CPU family. Clockspeeds will initially range up to 1.6 or 1.8GHz and performance is expected to be similar to Intel's Xeon offerings. But as always, we'll reserve judgement until we can actually evaluate two similarly configured servers side by side, for now all they have given us are SpecInt-2000 and SpecFP-2000 scores without disclosing the system configurations, so that doesn't tell us anything.
Nevertheless it looks like AMD is indeed trying to get some new and innovative products out of the door. Whether they'll be able to make a lasting impression, both in terms of features and performance, with their new 64-bit products remains to be seen though, we'll be sure to keep a close eye on any future developments.

Linux/Mac portability is nice, but not real critical, both are a much smaller market (in terms of sales, not necessiarlly units owned) than X-box or Windows. Hence, Direct3D is a logical choice for the primary renderer, given the goal.

2) Memory subsystem. The Athlon 64 has a memory subsystem derived from the Alpha EV7. Since these games are very memory-bandwidth bound, this should be a big speedup.

The fastest current single CPU would only decrease that number to about 40 minutes, which is still too slow.
A dual CPU solution would bring it down to 20 minutes, but again, if I ever wanted to render even 15 minutes of video, that would be 1 hr 40 mins of CPU time.
And forget doing anything else with the computer while it's rendering. It will start dropping frames like mad, and you have to start over.
Now a 4-way workstation is something that would work. With a 4-way 3GHz Opteron system, I could render in near real-time, and a regular sized MB, if not slightly oversized, could handle 4 procs.
SuperMicro is the only MB mfg. I know of that makes a 4-way board, but it's for Xeons and is insanely expensive ($1800 +/- $100) and that's before you add the overpriced CPUs.

You certainly won't get the fast memory pipeline access that the on board SMP systems will give you, but the cost of physically separate systems is lower.
Video and/or 3d rendering lends itself well to distributed tasks because you can effectively outsource each frame to a different processor and then put them back together later (AFAIK there are even systems that do this on the pixel level - but I know less about that than the fram based level).
IMO OpenMosix requires far less time in setup, and it seems to be more forgiving to different system makeups (some faster, some more ram, etc).
I use it for financial analysis and on a single system it would take me a few days to go through all of my data. each time I add a node to the system, it nearly halves the amount of time (Due to network bandwidth issues and different speeds of nodes it isn't ever as straightforward as just halving the speed each time a node is added).
I can put together a single node for under $400 (Athlon 2.1G and 256MB Ram - I don't need much ram for what I do) - so for a quad system, it would be $1600 in computers and about $100-200 in networking. You could then double that for the same cost of less (save when buying in bulk).
That is $3600 for an 8 processor system - I don't think you will ever see that in an on board configuration and the speed difference isn't enough that you would care (if something finishes 10 mins earlier, but costs $5K more, is it worth it? for video, probably not)?
The large issue with clusters is that as they grow in number, their physical space that they take up increases, as does power consumption, heat dissapation, and noise.

They had no clue what so ever.
I'm pretty impressed that the 64-bit box didn't suck more at UT than it did - 64-bits suck for applications where cache matters and 32-bits are enough. Not doing "terribly" is pretty impressive
I wish they would have run that "some kind of database benchmark" with a 20 GB working set, on the 64-bit box and a similarly configured 4-way P4 (any speed, take the 3G, it won't matter). Stuff 16-32 GB of memory in the machines, and see the 64-bit box wipe the floor with the competition.
Heck, why do people buy 700 MHz Sun UltraSPARC boxes for some of the biggest and busiest databases in the world? The P4 is faster clock-speed wise, and it's one helluwalot cheaper.
Quick answer: because 32-bits don't cut it, and clock speed is irrelevant when you are faced with either missing cache (64-bit) or missing RAM (needing a disk seek - 32-bit), for every single darn operation in your database.
All computers wait at the same speed. 64-bits allows you to stuff enough memory in a box so that you can wait for a L2 cache miss, instead of waiting for a disk seek. That's a few ns of waiting, compared to a few ms. Three orders of magnitude. 700 MHz versus 3GHz is insignificant in this light.
Ok, I'll stop ranting now. I totally agree that the clueless motherfsckers who did that article should be lined up against a wall and shot, for that "some kind of database benchmark" remark. Sigh, talk about not getting it...
Unfair Comparison. (Score:3, Interesting)
In my experience, properly ported OpenGL games on Linux (like RTCW) were faster than under Windows, but UT2003 is definately not the case. For that reason, these comparisons are way too early. I can't speak for the port to the Athlon64 architecture, but when it comes to the 32 bit version of UT2003 for Linux, it's very slow in comparison to the Windows release. This is what happens when you code a game for one platform, one API, and then try to port it to other operating systems.

There's a persistant myth that a 64-bit processor is twice as fast as a 32-bit processor, which is completely incorrect.
