Johan De Gelas heeft vandaag op Ace's Hardware het eerste artikel neergezet van een serie van drie waarin dieper wordt ingegaan op het design van de Pentium 4. Dit deel gaat over de geheugenstructuur van de Pentium 4 en er wordt uit de doeken gedaan hoe snel alle caches en geheugens zijn. Ook worden er wat vergelijkingen gemaakt tussen SDR, DDR en Rambus geheugen. Echt een stukje voor de liefhebber . Hieronder een hapje inleiding:
If you've already read our Pentium 4 review, you will agree that the performance of Intel's newest architecture can not be described in a few sentences. The 1.5 GHz Pentium 4 received a right hammering from both the Athlon 1100 and 1200 in raytracing, rendering, compiling, and several DirectX games. On the other hand, the Pentium 4 offered superior performance in Quake 3 and video encoding. Educated guesses were all we could offer you as explanation for the dubious behavior of Intel's "Netburst" architecture.
Nevertheless, this behavior sparked our interest. What bottleneck is keeping this unbelievably highly clocked monster from boasting stellar performance? After looking at all the benchmarks that we presented you, you might be tempted to think Intel's engineers have not done their homework. After all, a workstation processor should shine in rendering and compilation benchmarks. Simply assuming the Pentium 4 was designed for high clockrates, and that Intel has thrown all other considerations overboard, however, is a bit too simplistic. No, there must be more! Is it possible that the Pentium 4 will finally walk over the competition when the first optimized software arrives? When we unleashed some in-depth benchmarking on the best of AMD and Intel, we were surprised by many of our discoveries. We're sure you will be too.
