Benchmarks: 3DMark, Serious Sam, RTCW, Conclusions

3DMark2001 SE Source: MadOnion

3DMark2001 SE is the latest installment in the 3DMark series by MadOnion. By combining DirectX8 support with completely new graphics, it continues to provide good overall system benchmarks. 3DMark2001 SE has been created in cooperation with the major 3D accelerator and processor manufacturers to provide a reliable set of diagnostic tools. The suite demonstrates 3D gaming performance by using real-world gaming technology to test a system's true performance abilities. Tests include: DirectX8 Vertex Shaders, Pixel Shaders and Point Sprites, DOT3 and Environment Mapped Bump Mapping, support for Full Scene Anti-aliasing and Texture Compression and two game tests using Ipion real-time physics. Higher 3DMark scores denote better performance.

3DMark2001 SE Benchmark Results
Motherboard (FSB/Memory) 3DMarks Ranking
1. 8KHA+ 133/266 MHz 8644
2 KT3 Ultra 133/333 MHz 8795
3. KR7A-133RAID 133/266 MHz 8823
4. KR7A-133RAID 174/348 MHz 9201

Here, the KR7A-133RAID simply leaves its competition in the dust. Scoring almost 200 points higher then the 8KHA+ at stock speeds is quite a feat!

Serious Sam 2

Serious Sam 2 is a game that uses OpenGL and is a little more advanced than the now retired Quake III Arena.Higher numbers denote faster frames per second (FPS), and hence, better performance.

Serious Sam 2 (Normal 640x480 Little Trouble) Benchmark Results
Motherboard (FSB/Memory) (FPS) Ranking
1. 8KHA+ 133/266 MHz 174.6
2 KT3 Ultra 133/333 MHz 174.7
3. KR7A-133RAID 133/266 MHz 174.6
4. KR7A-133RAID 174/348 MHz 175.9

Serious Sam 2 (Normal 640x480 Valley of the Jaguar) Benchmark
Motherboard (FSB/Memory) (FPS) Ranking
1. 8KHA+ 133/266 MHz 62.1
2 KT3 Ultra 133/333 MHz 62.3
3. KR7A-133RAID 133/266 MHz 62.1
4. KR7A-133RAID 174/348 MHz 63.2

Serious Sam being more of a system benchmark places the KR7A-133RAID at the same level as the 8KHA+ and KT3 Ultra.

Return to Castle Wolfenstein

Source: ID Software

Return to Castle Wolfenstein is a relatively new game benchmark. However, RTCW takes up where Quake III left off and continues to form the basis of the first person shooter system stressing that QIII has become a hallmark for. Based upon the Quake III engine, RTCS is obviously going to be quite taxing on even a top end system. Higher numbers denote faster frames per second (FPS), and hence, better performance.

RTCW (640x480 atdemo6) Benchmark Results
Motherboard (FSB/Memory) (FPS) Ranking
1. 8KHA+ 133/266 MHz 60.6
2 KT3 Ultra 133/333 MHz 62
3. KR7A-133RAID 133/266 MHz 61
4. KR7A-133RAID 174/348 MHz 62.4

RTCW (640x480 atdemo8) Benchmark Results
Motherboard (FSB/Memory) (FPS) Ranking
1. 8KHA+ 133/266 MHz 167.7
2 KT3 Ultra 133/333 MHz 172.6
3. KR7A-133RAID 133/266 MHz 168
4. KR7A-133RAID 174/348 MHz 173.7

It's no surprise that the KR7A performs on par with the other boards. Seems here that the extra memory bandwidth the MSI KT3 Ultra has seems to help a bit since it scores just a tad higher then both KT266A boards at stock speeds.


The Abit KR7A-133RAID didn't disappoint us one bit during testing. Performance was on par with the Epox 8KHA+ (KT266A) and the MSI KT3 Ultra-ARU (KT333) which is very good to see. Stability of the KR7A-133RAID was near perfect with all crashes due to user error - even fitting out the board with four 256MB PC2100 DIMM's didn't compromise stability!

At $250 CDN, the KR7A-133RAID is the most expensive Athlon motherboard you can buy other then the nForce boards. With that price tag however, you get many things; six PCI slots, four DIMM slots an onboard IDE Ultra/133 controller. Abit's usual overclockablility comes standard.

On that note, the KR7A was a very good overclocking with the Mushkin High Performance PC2100. With that memory we were able to get the board as high as 174 MHz FSB! Using a stick of OCZ PC3000 DDR, the board was stable all the way up to 200 MHz FSB. However that was with relaxed memory timings which produced results lower then at 174 MHz with aggressive memory timings. We really appreciated the fact that Abit cleared the socket area of resistors so we could install larger heatsinks such as the Swiftech MCX462.

Not everything was perfect with the board however, our biggest complaint (and it really is a small one at that) is the location of the IDE RAID controller's and the Floppy drive connector.

Other then that, we were very happy with the board and whole heartily recommend the KR7A-133RAID to anyone who is thinking about buying a new Athlon motherboard. The KR7A proved itself to be stable enough to run important projects, and since it's a Abit board, it has enough to satisfy any overclocker!
