Effective speed is adjusted by current prices to yield value for money. Our figures are checked against thousands of individual user ratings. The customizable table below combines these factors to bring you the definitive list of top GPUs. See how consistently different GPUs perform with varying real world conditions. The charts also illustrate overall performance, popularity and rank. Save as guest. Average Bench: 8.
This isn't a great result which indicates that there are much faster alternatives on the comparison list. Strengths Avg. Locally-deformable PRT Bat NBody particle system Galaxy 8. This is an extremely narrow range which indicates that the ATI HD performs superbly consistently under varying real world conditions.
Weaknesses Avg. High dynamic range lighting Teapot Parallax occlusion mapping Stones 9. Average Bench Based on 23, samples.
Rank 8. GBR-User, 13 hrs ago. HD ESP-User, 2 hrs ago. Asus HD Matrix specifications. GPU and memory clocks are 20MHz higher. Our sample came as a bare card without a box or accessories. While the cooler design is more open than the stock HD heatsink, there is still plenty of plastic designed to direct airflow out the back. With the fans blowing straight down onto the PCB, there seems little reason to do this.
On the trace side of the card, only 7 screws are visible. The cooler is essentially a dual radial cooler design, but one heatpipe is connected to a narrow block of fins at the back, sitting next to a vent. Installed in our test-bed. Do so at your own risk. Note that all testing on the card was performed before the cooler was removed. The reference ATI RAdeon heatsink is composed of a massive copper block connected to two heatpipes. The Asus Matrix heatsink features a series of heatpipes snaking around the two fans and into a block of fins at the rear.
The fans are manufactured by Yen Sun Technology. It allows the user to change GPU and memory clock speeds, voltages, and fan control settings. GPU and memory voltages can be tweaked from 1.
We recommend only making minor adjustments and testing for stability after each change. Caution should be used when this amount of control is allowed. Incidentally, the Power Saving mode actually lowers the memory clock lower than iTracker allows if you do it manually. Also, undervolting the GPU below 1. For testing we used the Power Saving mode, but altered the 3D settings so they matched those of the Optimized and Gaming modes.
While the card has two fans, iTracker can only change how fast the smaller, auxiliary fan the one over the VRM section of the board spins. This means it can only be turned completely off or made to spin faster. It, along with power consumption measurements confirmed that both voltage controls were actually functioning and not just for show. By adequately cooled , we mean cooled well enough that no misbehavior related to thermal overload is exhibited. Thermal misbehavior in a graphics card can show up in a variety of ways, including:.
Any of these misbehaviors are annoying at best and dangerous at worst — dangerous to the health and life span of the graphics card, and sometimes to the system OS. This is a good indicator of how efficient the card is and will have an effect on how hot the stock cooler becomes due to power lost in the form of heat. The lower the better.
The software is left running until the GPU temperature remains stable for at least 10 minutes. If artifacts are detected by ATITool or any other instability is noted, the heatsink is deemed inadequate to cool the video card in our test system. Join Team ARP! Support Us!
