Nvidia's GTX 480: First Fermi Benchmarks!
Power and Connectivity
Since the new cards are so power-hungry, Nvidia’s engineers designed a sophisticated, heat-pipe based cooler to keep the GPU and memory within the maximum rated 105 degrees C operating temperature. When running full bore, the cooling fan spins up and gets pretty loud, but it’s no worse than AMD’s dual GPU Radeon HD 5970. It is noticeably louder than the single chip Radeon HD 5870, however.
The cooling system design helped Nvidia build a board that’s just 10.5 inches long, a tad shorter than the Radeon HD 5870 and much shorter than the foot-long Radeon HD 5970. Given the thermal output, however, buyers will want to ensure their cases offer robust airflow. Nvidia suggests a minimum 550W PSU for the GTX 470 and a 600W rated power supply for the 480 GTX. The 480 GTX we tested used a pair of PCI Express power connectors – one 8-pin and one 6-pin.
Unlike AMD, Nvidia is sticking with a maximum of two displays with a single card. All the cards currently shipping will offer two dual-link DVI ports and one mini-HDMI connector. Any two connectors can be used in dual panel operation. Current cards do not offer a DisplayPort connector.
Nvidia is also beefing up its 3D Vision stereoscopic technology. Wide screen LCD monitors are now available with 120Hz refresh support in full 1920x1080 (1080p) resolution. One card will drive a single 1080p panel. If your wallet is healthy enough to afford a pair of GTX 400 series cards, 3D Vision is being updated so that you can have up to three displays running in full stereoscopic mode.
What’s the price of all this technological goodness? Nvidia is targeting a $499 price point for the 480 GTX and $349 for the 470 GTX. Actual prices will vary, depending on supply and overall demand.
The burning question, of course, is: when can you get one? Rumors have been flying around about yields and manufacturing issues with the Fermi chip. Nvidia’s Drew Henry stated categorically that “tens of thousands” would be available on launch day. We’ll just have to wait to see what that means for long term pricing and availability.
It’s possible we’re seeing the end of the era brute force approaches to building GPUs. The 480 GTX pushes the edge of the envelope in both performance and power consumption – and that’s with 32 compute units disabled. So even at 250 watts or more, we’re not seeing the full potential of the chip.
In the end, the 480 GTX offers superlative single GPU performance at a suggested price point that seems about right. It does lack AMD’s Eyefinity capability and its hunger for watts is unparalleled. Is the increased performance enough to bring gamers back to the Nvidia fold? If efficiency matters, gamers may be reluctant to adopt such a power-hungry GPU. The performance of the Radeon HD 5870 is certainly still in the “good enough” category, and that card is $100 cheaper and consumes substantially less power. If raw performance is what counts, the 480 GTX will win converts. Only the fickleness of time, availability and user desires will show us which approach wins out over the long haul.
GTX 480: Best Single GPU Performance
Our test system consisted of a Core i7 975 at 3.3GHz, with 6GB of DDR3 memory running at 1333MHz, running on an Asus P6X58D Premium motherboard. Storage included a Seagate 7200.12 1TB drive and an LG Blu-ray ROM drive. The power supply is a Corsair TX850w 850W unit.
We’re adding in performance of 3DMark Vantage as a matter of interest; FutureMark’s 3D performance test is increasingly antiquated, and not really a useful predictor of gaming performance.
We tested six different graphics cards, including a standard Radeon HD 5870 and the factory overclocked Radeon HD 5870 XXX edition. We also included results from older Nvidia cards, including the aggressively overclocked eVGA 285 GTX SSC and a reference 295 GTX. Also included was an HIS Radeon HD 5970, built with two Radeon HD 5870 GPUs.
For the most part, the Radeon HD 5970 won most of the benchmarks. One interesting point is the recently released Unigine 2.0 DX11 test. If you scale up tessellation to “extreme” the GTX 480 edges out the dual GPU AMD solution.

The GTX 480 wins about half the benchmarks against the single GPU Radeon HD 5870, and essentially ties in the rest. Where it does win, however, it generally wins big.
The GTX 480 “wins” in another test – power consumption – but not in a good way. The system idled at 165W with the GTX 480, exceeded only by the dual GPU HD 5970’s 169W. However, at full load, the 480 GTX gulped down 399W – 35W more than the 5970 and fully 130W more than the Radeon HD 5870 at standard speeds.
Up next, how do the cards perform under more challenging conditions?
