An anonymous reader sent us a Firingsquad article
on the AMD K7, which provides some benchmarks comparing the K7 and the PIII.

When buying a CPU Mhz doesn't matter, it is price vs performance that matters. CPUs of equal price should be compared in these kinds of tests.

There are reasons integer and float still exist. (Score:1)
Floating point is different. We're familiar with decimal fractions because we're taught arithmetic in decimal. Binary floating point - which can be made very fast in silicon - is a strange beast. Binary floating point is good when the numeric results stay meaningful only for the PC. Such as 3D rendering. This is because binary floating point has different error characteristics than decimal floating point. You can't represent 0.1 accurately in binary.
But integer calculations are simpler and faster to do in silicon and many applications don't need binary floating point because they can either synthesized decimal floating point (with it's familiar error characteristics) or they simply don't need fractions.

Integer speed vs. Floating point speed. (Score:1)
When reading those benchmarks I always wonder whether the integer results and the floating point results are in the same scale.
If they are on the same scale, would not it be much better to do all the calculations in float? (If you've got huge numbers, you loose some accuracy, and you cannot use floating point in the kernel, but what about the rest?)

I agree with the sentiment; 70 fps can cause motion sickness. :o> Reason why some people refuse to play Quake and EverQuest; it's not because they don't like playing games, they just get physically sick of watching those polygons.
18 fps was the quality of most .mov videos when Quicktime 1.5 was the big, big deal. I remember those looking choppy as hell. Maybe different eyes are more or less sensitive than "normal" eyes. I dunno. All I know is that you can't tell geeks they can't use technology if it presents itself, so by next year we all could be convulsing in epilepsy.

Incorrect numbers given (Score:3)
The human eye percieves smooth motion at about 20 frames per second.
No. It varies depending on contrast and ambient lighting, but 60 frames per second is often cited for purposes of generalization.
TV (in the US at least) is broadcast at 24 fps
No, U.S. TV is 30 full frames per second (interleaved from 60 half frames per second to reduce flicker). European TV is 25 frames per second, due to 50 half frames per second interleaved. (In both areas, there's a historical and RF noise connection to the 60/50 hertz power lines.)
movies are usually at 30 fps
That doesn't ring a bell; I think it's actually 24 frames per second double-shuttered to give an effective 48 fps. I may be misremembering the precise numbers there.
At low resolutions used for games (640x480, 800x600), many graphics cards can supply the monitor with a vertical refresh rate of 85 Hz, but at high resolutions, all but the most expensive cards (things like cards designed for CAD, such as the FireGL cards) drop off in maximum vertical refresh rate.
Yes and no; what you said is very misleading, since recent higher end cards from Matrox, and the Nvidia TNT2, retain high frame rates even at the highest of resolutions (approaching almost 2000x2000 these days). Now it's true these are "high end cards", but that's in a consumer sense of very roughly $200, they are *not* high end CAD market cards, which can cost thousands of dollars.
I found 1024x768 to be a much more desirable resolution for playing quake. So, what use is it if the Athlon can push out frames faster than your monitor can display them???
That's largely a matter of taste. It's true that not everyone has high quality monitors, but on the other hand, a fair number of people (including gamers) do in fact have high bandwidth monitors. Your taste (and monitor) isn't everyone's.
Granted, there are other areas where fast 3D performance is a big plus (rendering movies, etc.), but for games, 70fps is absolutely pointless
Now that goes way too far. Actually, a monitor refresh rate of a minimum of 70 hertz is highly recommended to avoid perceptual flicker under adverse lighting conditions -- this varies from person to person, but many of us see flicker, at least in peripheral vision, almost always with 60 hertz displays.
If you had said "85 fps monitor refresh rate is pointless", you'd be closer to the truth, although that too is debatable for more complex reasons that we're getting into here.
(I usually use 1600x1200 32 bit color 80 hertz for non-game (2d) purposes, and for games, usually have to drop it down, since I don't yet have a TNT2 nor voodoo3. The highest res of my voodoo2 is less than that of my 2d card.)

We need more polys per second... (Score:2)
Off-the-shelf, AGP 3D cards now are competitive in fill rate even with sweet SGI workstations, but for the geometry portion of rendering PCs get blown away, and seriously blown away with high polygon scenes. Until we get PC dedicated hardware to do geometry acceleration and not just texture filling (doesn't the G200/G400 do some geometry on the card?), we need heavy CPU FPUs to do it for us.
Sure, spitting out a bunch of 60 poly models at 120 fps might be overkill, but displaying 400 poly models at 60 fps won't be. In the near future I can imagine game designers giving "low poly -> high poly" options in the video setup just as they give "320x200 -> 1600x1200" options today to balance quality vs. performance. (doesn't half life do this to some extent already?) We're seeing the first 3D engines that render bezier curves by breaking them up into polys (does Q3 do this when the level is compiled or when it's played?) and the more polys you use the smoother it looks. Hell, the more polys you use the more cool stuff you can do with background effects (remember how the Unreal flies blew away the Q2 buzzing dots?) and realistically moving human models. And man, some of us want to play games with that kind of image quality.
Oh, yeah, and it'll be a big boon for scientific computing, video editing, professional rendering, etc. when they're reasonable on cheap x86 hardware too.

Movies run at 24 FPS.
It is a well stated and known fact that 24 FPS and even 30 FPS give away errors in things that are filmed (ie spinning objects like wheels). To fool the human eye into thinking it is seeing real motion it needs not only 60 FPS but motion blur as well. The newest generation of game consoles can do this... Some people can easily tell the difference between 70 and 60 FPS. If you can't then count yourself as lucky because you will be satisfied with less.

Re:Who needs 70 frames per sec? (Score:1)
Going from 70 FPS down to 30 FPS is quite a visible jolt (to me anyways). The way around this is to have enough CPU power available to keep the frame rate as high as possible in complex scenes.
One way is to boost the CPU power dramatically. Another (similar) way is to use SMP, which is what the yet-to-be-released new version of Q3Test has.

Forget the hand, use a rubber band... (Score:2)
Also, the reason that a monitor is partially black isn't really an aliasing thing. It's just that any CRT is really only partially lit at any given time. The entire image never exists on the screen at once, it only exists in video memory and your brain. Simply taking a still photograph of a TV will demonstrate this.
On the other hand, when you see a monitor on TV the black band will be moving either up or down the screen at some frequency. The rate at which the band moves is an aliasing artifact whose rate is determined by the refresh rate of the monitor and the rate at which it is being "sampled" by the camera.

This should increase the motivation for the continuation of gains in performance and cost / performance ratio. In terms of what Joe Doakes average hobbiest gets for the money, I think the optimum design right now is a dual processor system using a not-quite bleeding edge CPU - say a PII 450 or therabouts. The cost of adding a second CPU to a system seems to be less than the cost of bumping up the clock another hundred or so MHZ. This does not account for improvements in internal efficiency, but you do get a lot more bang for the buck with 2 CPU's. The more people who have multiprocessor systems, wether SMP, clusters or even shared-memory systems the faster we will see the evolution of new software paradigms that will truly advance the state of the art.
