More benchmarks and the point behind all this....

Sisoft Sandra 2002 Source: Sandra

Sandra is designed to test the theoretical power of a complete system and individual components. The numbers taken though are again, purely theoretical and may not represent real world performance.

SiSoft Sandra 2001 Benchmark Results

Memory Benchmark

1. 256MB Crucial PC1600 1542 MB/s / 1480 MB/s
2. 256MB Crucial PC2100 2072 MB/s / 1993 MB/s
3. 256MB Mushkin Enhanced PC2100 2077 MB/s / 1995 MB/s
4. 256MB Corsair XMS2400 2069 MB/s / 1991 MB/s
5. 256MB KingMAX PC2700 2072 MB/s / 1993 MB/s
6. 256MB OCZ PC3000 2070 MB/s / 1994 MB/s

As we can see, only the RAM running at PC1600 offers less bandwidth and since the other sticks of memory are all running at PC2100 speeds, they all perform within a few MB/s of each other.

PCMark is a new benchmark from our pals at MadOnion which a whole system benchmark. It can be used on desktop PC's, Laptops and even Workstations and tests everyday computing from home to office usage. PCMark specifically stresses the CPU, memory subsystem, graphics subsystem, hard drives, WindowsXP GUI (if WinXP is used), video performance and even laptop batteries. This benchmark was released March 12, 2002 and can be downloaded from Madonion if you would like to give it a test run on your computer for comparisons sake... don't cry to hard when you compare your numbers to the ones listed below!

PCMark2002 Benchmark Results


PCMarks Ranking
1. 256MB Crucial PC1600 2616
2. 256MB Crucial PC2100 3233
3. 256MB Mushkin Enhanced PC2100 3231
4. 256MB Corsair XMS2400 3235
3. 256MB KingMAX PC2700 3234
4. 256MB OCZ PC3000 3230

Are we staring to see a trend here? You bet it. All the memory running at PC2100 speeds performs at the same speed since they have the same memory timings in the BIOS. The only stick of RAM that lags behind is the Crucial PC1600 because it runs slower.

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. 256MB Crucial PC1600 7865
2 256MB Crucial PC2100 8664
3. 256MB Mushkin Enhanced PC2100 8646
4. 256MB Corsair XMS2400 8675
5. 256MB KingMAX PC2700 8635
6. 256MB OCZ PC3000 8651

Again, we see that the PC2100 and higher class DDRAM performs the same because they're all running at the same speed. Because the system is bandwidth starved when running the memory at PC1600 speeds, the score is much lower.

Quake III Arena

Source: ID Software

Quake III Arena is a First Person Shooter (FPS) that revolutionized gaming as we know it. Using multiple light sources and having graphics textures that can fill videocards, even after 3 years it's still able to bring a cutting edge system to its knees.

Motherboard (FSB/Memory) 3DMarks Ranking

4. 256MB Corsair XMS2400 282.1
5. 256MB KingMAX PC2700 281.6
6. 256MB OCZ PC3000 282.3

Quake III Arena Fastest nv15demo
Motherboard (FSB/Memory) 3DMarks Ranking
1. 256MB Crucial PC1600 64
2 256MB Crucial PC2100 80.3
3. 256MB Mushkin Enhanced PC2100 80.3
4. 256MB Corsair XMS2400 80.3
5. 256MB KingMAX PC2700 80.3
6. 256MB OCZ PC3000 80.4

It's well known that Quake III love memory bandwidth and only the PC1600 DDR trails. Everything else is closely packed together way ahead. The nv15demo is more CPU limited then anything else, but it's still apparent that the CPU needs memory bandwidth.

What was the purpose of this article?

Why did we spend the time to state the obvious? Did we though?

I for one know a few people who always insist on using the fastest things available in their computers but yet they don't overclock.

If you're not going to push your system beyond it's rated spec's, you really honestly don't need that cool looking BGA RAM on the KingMAX or those cool copper heat spreaders on the OCZ PC3000 DDR.

As we can see here, the only stick of RAM which is left behind is the Crucial DDR when it's running at PC1600 speeds, it simply doesn't have enough memory bandwidth to feed the Athlon processor.

The rest of the memory sticks perform identically because they're all running at the same speed with the same RAM settings regardless of whether they are DDR200-PC1600, DDR266-PC2100, DDR300-PC2400, DDR333-PC2700, or DDR366-PC3000.

There you have it. If you're not going to be overclocking you can pretty much get any ole stick of good quality PC2100 DDR RAM for your system, since at stock speeds it be performing as well as the more expensive stuff like PC2700 and PC3000. However, if you're more of an enthusiast, it is worth your while to pick up some higher quality DDRAM since it will allow you to go higher in your overclocking adventures.
