AMD has come quite far since the days when the K6-2 or K6-3 tried to play
catch-up with Intel’s offerings. First, it was the Athlon in its different
forms–K7, K75 and Thunderbird–that gave Intel’s PIII a run for its money
in the high-end segment. Then, the Duron released in June last year did the same
to the Celeron in the entry-level market.

The Duron is based on the Athlon K7 core, minus 12 million transistors. It
has a 128 kB L1 cache and a 64 kB L2 cache, both running at the same speed as
the core itself. All Duron processors have a 462-pin Socket A interface, which
is the same as Thunderbird’s. The latest Duron runs on 800 MHz and, going by
our tests, is quite a performer.

For our tests we used a Creative GeForce display card, a VIA VT82C686A
chipset motherboard, and 128 MB RAM. We ran the same set of tests on a Celeron
600 MHz based machine, with an Asus CUSL2-C motherboard and the same
configuration. For the benchmarks, we used Business Winstone 99, Winbench 99,
Quake III Arena and 3D Winbench 2000. Whereas Winstone and Quake III help us in
looking at the larger picture, specialized processor tests in Winbench and 3D
Winbench stress the CPU and measure its performance.

So, how did the Duron 800 fare? We wouldn’t be too far off the mark if we
said that perhaps the only reason that the Duron is called a low-end processor
is because of its price. It was able to pump out 108 frames per second (fps) in
Quake III at 640×480 resolution with 32-bit color depth, which is about 12
frames more than its older cousin, the Duron 700. These dropped to about 82 fps
at 800×600 with 32-bit color depth. Nevertheless, these are really good frame
rates for a 3D game, resulting in very smooth game play.

In Business Winstone 99, which measures performance in running normal
productivity applications like office suites and Web browsers, our test setup
got a score of 28.8, which is higher than the Duron 700 by only about 0.8 marks.

We then moved to benchmarks that stress the processor specifically, which
include CPU Mark and FPU Mark of Winbench, and the 3D Winbench 2000 processor
test. The CPU Mark showed a 12.6 percent gain, while it was ahead in the other
two tests by about 10 percent each. We also tried to see where the new Duron
stands compared to a Celeron 600 MHz–Intel’s processor for the entry-level
segment. The scores for the Celeron were way below those of Duron 800, and even
those of Duron 700. Unfortunately, we didn’t have the Celeron 700 MHz for
comparison. Another Celeron version, which runs at 800 MHz on 100 MHz FSB, was
announced only recently; so we couldn’t catch it on time.

Overall, Duron 800 is the way to go for entry-level PCs. Another interesting
point here is that entry-level processors are fast approaching the GHz limit.
So, every desktop may well have one soon.
