Test Setup/Performance Tests

We also ran a number of performance tests to let us see the difference between a reference factory clocked and factory overclocked X1900. This will also give us a look at how the X1900 XTX and XT numbers compare, taking into consideration the different user overclocks. We tested three games at 1600x1200 resolution with and without AA enabled. The games that we used (Battlefield 2, Quake 4, and Halflife 2: Lost Coast) had been chosen because they represent a wide range of game engines. We also tested these games with sound disabled. This is the test system that we used:

NVIDIA nForce 4 motherboard
AMD Athlon 64 FX-55 2.6 GHz Processor
1 GB OCZ 2:2:2:6 DDR400 RAM
Seagate 7200.7 120 GB Hard Drive
OCZ 600 W PowerStream Power Supply

Again, we see how closely the overclocked X1900 XTs perform to the reference X1900 XTX in each of these games. As we expected, even at 2048x1536, the frame rates in each of these games are high enough to provide smooth gameplay, even with AA enabled. These benchmarks give us a solid demonstration of the X1900's raw power. On the high end, as with Splinter Cell Chaos Theory, we can see how the different overclocks gave similar performance results. The Sapphire XTX logically shows slightly higher performance in general than the others because of its high overclock. The fact that all of these numbers are so close together in the different games is interesting, and is further evidence that the X1900 XT might be a better choice over the XTX given performance and price.

    Sadly I don't think Gigabyte is an ATI partner, but I do hope Sapphire is working on better cooling for the X1900 series. Asus is NVidia but might also make ATI cards? I don't remember. If they try to passively cool it like with their 7800GT they just better do it well enough that it's not roasting itself to death at 70+ degrees Celsius. =/

    In pro music applications 0.1db is considdered inaudioble but 0.7db - everyone can hear that change - Unless there is a louder component overall in the system.

    49.x db is still ridiculously loud, no matter how much an exponential change it is from 50.x.

    The loudest part in my current rig is around 37db. Claiming 49anything is quiet is RUBBISH and it most certainly is NOT a significant improvement over 50.x db. A slight improvement would be 47db instead of 52 db. A significant improvement would be 42db instead of 52db. A worthwhile improvement would be replacing those terrible fan designs with a Zalman/AC style cooler and offering that stock like Sapphire has in the past.

    Come talk to me when it's at 45-47db at 100% fan speed and I'll be interested in buying it (because I'll drop it to ~20% fanspeed with ATITool like I do my current stock-Zalman-cooled Sapphire X800XL and that'll be close enough to this curent level of quiet to be acceptable.

    <^ Broke owner of a Sapphire X1900XT

    "The X1900 is one of those cards that is on just about everyone's wish-list. Those who are lucky enough to own one are probably the envy of their friends and also perhaps became broke from the purchase."
