As we alluded in our explanation of Rapid Execution Engine and branch mispredictions, the Pentium 4’s integer performance isn’t all that impressive. It’s much more difficult to predict integer instructions than anything else. These rather low scores, compared to FPU scores, signify more branch mispredicts and the inherent inability to take shortcuts because of it.
With the i850 chipset supporting full Ultra ATA 100 specifications, we see our IBM 75GXP drive nearly double the performance of a standard Ultra ATA 66 drive. Check out the buffered read scores -- 74MB/sec. Write scores are equally impressive; clocking in at a cool 54MB/sec. Ultra ATA 100 isn’t just a new name for a new gimmick, it really works and works quite well. What does this mean to you? It means faster boot times, faster load times, and drive access across the board.
In memory tests, the Pentium 4 with its dual-channel RDRAM kicks the silicon out of the Athlon. Thanks to the new AGTL+ bus being quad pumped at 100MHz to be effectively 400MHz, the Pentium 4 takes the lead by an enormous amount. If you think this is impressive, take a look at memory scores with SSE2 optimized instructions. SiSoft Sandra 2001 (cont.)
Believe it folks. The Pentium 4’s memory bandwidth coupled with SSE2 optimized instructions give the Athlon and the Pentium III a big kick in the ass. There’s no doubt about the potentials of the Pentium 4. SSE2 indeed improves numbers and performance. Just wait until you see your applications and games get optimized for SSE2. I personally can’t wait to see the change.

3DMark2000
In 3DMark2000 the Pentium 4 takes the lead with a few hundred points. Thanks to the speed of the new AGTL+ bus and speedy RDRAM, the processor really shows off increases. And with Intel able to increase speeds at will, we’ll see more significant increases as they come. Intel should have less trouble increasing speed on the Pentium 4 than AMD with its Athlon, as there seems to be plenty of room for increases.
In 32-bit mode, we see Intel hold the lead again, this time with a slightly higher lead at lower resolutions and flattening out at high resolutions because of video card bottlenecks. We’re already talking about bottlenecks with a GeForce2 Ultra. Crazy, isn’t it?
3DMark2000 CPU Marks
3DMark2000 really shows off the Pentium 4’s multimedia skills. This chip is definitely optimized to run multimedia applications. Your favorite games should also blaze along on the Pentium 4’s new NetBurst architecture. Many of the new features like a 400MHz bus, Hyper Pipeline and Advanced Dynamic Execution really come into play, increasing overall enjoyment of games, video and sound.
VideoMark2000
The Pentium 4 scores a few points higher than the Athlon showing that its undisputed 400MHz AGTL+ bus is now slouch when it comes to bandwidth. We can definitely appreciate the memory bus running at 400MHz too care of the dual-channel RDRAM’s.
Let’s take a look at the Pentium 4’s Quake 3 Arena performance.
