DDR2 VS GDDR3? What's up with that?

The main advantage DDR2 has over good ole DDR memory is that it runs on a lower voltage, which lowers the power requirements, and allows it to scale higher with a small latency penalty.

GDDR3 (Graphics Double Data Rate3) takes this one step further, requiring less voltage than DDR2, and scaling even futher (though with some latency penalty). While the motherboard industry is making the transition from DDR to DDR2 memory, right now GDDR3 is only used on graphics cards. There are no current plans to migrate GDDR3 to the motherboard level - but who knows what the situation will be a year or two down the road. GDDR3 and DDR2 do share one thing in common, they are only packaged in BGA modules - leaving the old TSOP-II to be finally retired.

Micron were first out of the gate with GDDR3 DRAM modules, but the memory found on the Albatron GeForceFX 5700 Ultra is actually using Samsung K4J55323QF-GC20 GDDR3 DRAM. Compared to the Samsung K4N26323AE-GC22 DDR2 DRAM modules we find on earlier cards, the Samsung GDDR3 memory requires just 2.0V compared to 2.5V for DDR2. This which should help ease up on power consumption. However, as GDDR3 RAM runs with an even higher latency than DDR2, nVIDIA have had to clock the memory 50 MHz higher as well. This should offset any performance penalty that GDDR3 has over DDR2.

Overclocking the FX5700U3!

As usual we started with the core overclocking first; from 450 MHz we slowly went up a few MHz at a time. The core was a pretty good overclocker and the FX5700U3 went all the way up to 571 MHz before it started to have any problems. Anything higher though, and the computer would lock up when running any 3D application.

Since this is the first time we've dealt with GDDR3 we really don't know what to expect from the memory... but with 2ns DRAM we were hoping to hit some nice speeds. By default the memory is clocked at 950 MHz, 50 MHz higher than regular GeForceFX 5700 Ultra DDR2 based videocards. This is done to make up for a small latency penalty.

Not surprisingly we were able to crack the 1 GHz mark quite easily, but we were not able to go much higher than that. The maximum speed the FX5700U3 memory reached 1.02 GHz - if we tried to go higher we'd be greeted by artifacts like in the Raiders of the Lost Arc... you remember the big artifacts that spit out poison tipped darts, gigantic rock bowling balls, and all that fun stuff? Same thing here. :-)

By combining DirectX8 support with completely new graphics, it continues to provide good overall system benchmarks. 3DMark2001SE 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 numbers denote better performance.

It shouldn't be any surprise that the Albatron GeForceFX 5700U3 performs the same as the Gigabyte GeForceFX 5700 Ultra. Overclocking boosts the score a bit.
