Benchmarks: UT2004, Doom3

Unreal Tournament 2004

Source: Epic

Unreal Tournament 2004 is the sequel to the highly popular UT2003 and uses the very latest Unreal Engine technology. Unreal Tournament 2004 employs the use of Vertex and Pixel Shaders and it's recommended that you use a DirectX 9 videocard if you plan to play with all the bells and whistles enabled. Higher numbers are better.

UT2004 is a bandwidth-hungry benchmark, and it exposes our Intel dual-core test platform's weaknesses again. Interestingly, this benchmark benefited noticeably from running under 64-bit Windows. The Athlon64 X2 4800+ had some issues with UT2004 in 32-bit mode.

Doom 3

Source: id Software

Doom 3 is the most advanced OpenGL game to date, it takes advantage of the latest videocard technology and pushes the processing power of the CPU to its absolute limits. At its highest setting Ultra quality, texture sizes pass the 500MB mark which means even tomorrows videocards will have a hard time running everything. The framerates in the game itself are locked at 60 fps so anything above that point is wasted. Each test is run three times and with the third run being recorded. Higher numbers are better.

Doom3 Benchmark Results
LQ 640x480: Points Ranking
Pentium 4 540 88.5
Athlon64 3800+ 102
Athlon64 4000+ 115.7
Athlon64 X2 4800+ 114.9
Athlon64 X2 4800+ 64-bit 122
Pentium D 840 91.2
Pentium D 840 (4.02GHz) 104.9
Pentium D 840 64-bit 97.5

Doom3 also benefits greatly from 64-bit Windows XP when running on the Intel Pentium D 840. This is good news for gamers, especially as 64-bit video drivers can only get better with time. The Pentium D 840 derives little benefit from dual-core here, though it does manage to best the Pentium 4 540 by about 3FPS. The AMD dual-core processor holds the same advantage over the Pentium D that its single-core bretheren hold over the Pentium 4 processors in Doom 3.
