3D Gaming Performance
When it comes to most 3D games there's generally very little performance to be found by heavily optimizing for SSE2 or 3DNow! on either of these processors and thus the performance is mostly dependent on the overall platform (e.g. FPU capabilities, chipset, memory latency/bandwidth, cache latency/bandwidth, etc...). This makes gaming benchmarks the most important when doing a chipset comparison since it's much easier to see performance differences between chipsets.
We'll start off with our favorite 3D gaming benchmark - the Unreal Performance Test 2002. For an explanation of what this test is and why it is so significant, be sure to read our 15-way GPU Shootout that we used to introduce the test. In short, the benchmark uses the current build of the Unreal Engine (that will power games such as UnrealTournament 2003 and Unreal II) and serves as a great indication for future performance in games that use the engine.

47.8Although VIA has had much more experience in producing DDR memory controllers than Intel, the 845G's GMCH is able to offer performance equal to VIA's finest DDR333 memory controller. This is one of those situations where sheer R&D budget can outshine production line experience.

Under Quake III Arena we're able to see the largest lead the P4X333 ever holds over the 845G. At 4%, the performance advantage isn't enough to be even remotely noticeable to end users.
Our final two benchmarks paint a similar picture to what we've seen throughout this entire review - the 845G and P4X333 are effectively performance equals.
