DailyTech spends more quality time with NVIDIA's upcoming GeForce 8800GTX
NVIDIA is set to launch its
upcoming G80 GeForce 8800GTX and 8800GTS graphics cards next week
snagged a GeForce 8800GTX board to run a couple quick benchmarks on. The GeForce 8800GTX used for testing is equipped with 768MB of GDDR3 video memory on a 384-bit memory bus
as previously reported
. Core and memory clocks are set at 575 MHz and 900 MHz respectively. Other GeForce 8800 series features include
128-bit HDR with 16x anti-aliasing
NVIDIA’s Quantum Physics Engine
Previous NVIDIA graphics cards in single card configurations were limited to lower levels of anti-aliasing. With the GeForce 8800 series, users can experience 16x anti-aliasing with only a single card.
has verified the option is available in the NVIDIA control panel.
The physical card itself is quite large and approximately an inch and a half longer than an
AMD ATI Radeon X1950 XTX
based card. It requires two PCI Express power connectors and occupies two expansion slots. An interesting tidbit of the GeForce 8800GTX are the two SLI bridge connectors towards the edge of the card. This is a first for a GeForce product as SLI compatible graphics cards typically have one SLI bridge connector.
Having two SLI bridge connectors onboard may possibly allow users to equip systems with three
GeForce 8800 series graphics cards. With two SLI bridge connectors, three cards can be connected without any troubles. NVIDIA is expected to announce its
nForce 680i SLI and 650i SLI
chipsets with the GeForce 8800 series.
NVIDIA nForce 680i SLI and 650i SLI based motherboards
are expected to have three PCI Express x16 slots.
Moving onto the performance
has selected Half Life 2: Lost Coast, Quake 4, Prey and 3DMark06 for benchmarking. These games and applications were selected as other games use the same game engine. In addition to performance tests,
was also able to measure power consumption.
The test system configuration is as follows:
Intel Core 2 Extreme QX6700
NVIDIA nForce 650i SLI based motherboard
NVIDIA GeForce 8800GTX
PowerColor ATI Radeon X1950 XTX
Western Digital Raptor 150
Radeon X1950 XTX
Kicking off the benchmarking festivities is 3DMark06. NVIDIA’s GeForce 8800GTX scores 59% higher than ATI’s current flagship. This isn’t too surprising as the GeForce 8800GTX has plenty of power.
Half Life 2 4xAA/16xAF 1600x1200
Radeon X1950 XTX
Quake 4 4xAA 1600x1200
Radeon X1950 XTX
Prey 4xAA/16xAF 1600x1200
Radeon X1950 XTX
Half Life 2: Lost Coast loves the GeForce 8800GTX. Here the GeForce 8800GTX is able to show significant performance gains over AMD’s ATI Radeon X1950 XTX—approximately 92%.
Quake 4 shows similar gains as Half Life 2: Lost Coast too, an approximate 92% improvement.
Prey is based on the same game engine as Quake 4. However, Prey shows smaller performance differences between the GeForce 8800GTX and ATI Radeon X1950 XTX, albeit its still 60%.
Radeon X1950 XTX
Power consumption was measured using a Kill-A-Watt power meter that measures a power supply’s power draw directly from the wall outlet. The power supply used in the test system is a Thermaltake Toughpower that carries an efficiency rating up to 85%.
previously reported NVIDIA recommends a 450-watt power supply for a single GeForce 8800GTX graphics card
. This isn’t too farfetched of a recommendation. Power consumption of NVIDIA’s GeForce 8800GTX isn’t as bad as expected. When compared to AMD’s current flagship ATI Radeon X1950 XTX, the GeForce 8800GTX only consumes 24% more power at idle. The power consumption differences under load decreases to around 4%. Considering the performance differences, the GeForce 8800GTX is no worse than AMD’s ATI Radeon X1950 XTX in terms of performance-per-watt.
Expect NVIDIA’s GeForce 8800GTX and 8800GTS graphics cards to be available next week. As NVIDIA has had plenty of time to ramp up production and ship out cards, this will be a hard launch with immediate availability.

Could we get some demo settings/info? Those ATI scores are very very low...

I've no doubt there's a very good reason DT got less than half the scores AT got with their xtx at the same res/aa levels in Q4 on a similar rig, but it would be good benchmarking practice to explain why this is so ;)
I'm well aware that scores will differ significantly between timedemos used, AT's testing notes say they used a mix of indoor and outdoor gameplay (and are roughly in line with the results elsewhere on the web for q4/xtx/16x12/4xAA), but this is a dramatic difference...
If you set out to make a timedemo to bust the cards right down and let the G80 show us what it's capable of, that's great, but some explanantion of this would be nice ;)

ya considering other sites that now have reviews...
the numbers here, DON'T even come close to results on
other sites with the same suppossed settings (resolution and AA, etc)
this card fluxuates all over the place, i do see a 60% gain in some cases, in others, hardly any gain (unless you play on 2000+ resolution....ahem....)
