NVIDIA GeForce GTX 570 1.25GB Graphics Card Review
Another GF110 Part
For the latter half of 2009, the review schedule at PC Perspective was dominated by graphics cards from AMD as we saw the entire HD 5000 series come to fruition. Since then, NVIDIA has slowly but surely caught up with numerous releases like the GTX 480, 470, 460 and so on, and more recently, the GeForce GTX 580 based on the newer GF110 GPU.
Today we are looking at another new card from NVIDIA in the GTX 500-series, the GeForce GTX 570. As you might expect from the name, the GTX 570 is a slight step below the GTX 580 in terms of performance but turns out to be a noticeable step lower in price: $349 versus $529.
The GeForce GTX 570 is based on the same GF110 GPU that the GTX 580 is, a slightly revised version of the original Fermi-architecture.
contrary) and has not dropped features like ECC to reach these
performance levels. The secret to NVIDIA's improved performance and
yield comes from a monitoring and rearranging of the transistor paths
that caused the most leakage on GF100 in real-world environments.
NVIDIA's engineers then rearranged many segments of the die to better
improve efficiency and power consumption finally allowing them to enable
the full power of the architecture as GF110.
There have been some other architectural enhancements made on
the GF110 GPU as well including a full speed FP16 texture filtering
addition and improved Z-cull efficiency. These clock-for-clock
improvements in the GPU design offer performance improvements of
anywhere from 5% in Metro 2033 to 13% in Dirt 2 based on NVIDIA's own testing.
Remember this diagram that we have shown you so many times before?
The ROP count on the GTX 570 is 40 resulting in a 320-bit memory bus and slightly lower total memory throughput than the GTX 580.
It might be just as interesting to compare the new GTX 570 to the original GeForce GTX 480 card that shares similar specs.
- GeForce GTX 570 versus GTX 480
- 480 vs 480 CUDA cores
- 60 vs 60 texture units
- 40 vs 48 ROPs
- 732 MHz vs 700 MHz core frequency
- 1.25GB vs 1.5GB memory size
- 950 MHz vs 924 MHz memory frequency
So while the shader performance should be higher on the GTX 570 the memory performance and AA performance might be slightly faster on the original GTX 480. I should note though that the GTX 480 will be selling out very soon, what is in the market is all that will be released, so the GTX 570 is effectively replacing it with a lower price.
