When all where occupied with the first graphics chips DirectX 10 from AMD, R600, NVIDIA comes on with new high end card . The new card is similar to The geforce 8800 GTX but with higher frequencies and better cooling for always higher performances. Two weeks before the arrival of R600, NVIDIA officially announced this new card . We have here the occasion to test the GeForce 8800 Ultra, and to compare it with GeForce 8800 GTX From Asus and eVGA.
GeForce 8800 Ultra : specifications
Since November, the GeForce 8 range family grew rich with the first arrival of GeForce 8800 GTS 320 MB, then recently with medium range GeForce 8600 GTS, GeForce 8600 GT and other alternatives directed to low price range.
VS the old family GeForce 8, The GeForce 8800 Ultra takes again an identical architecture, in particular with the number of stream processor. Like GeForce 8800 GTX, The GeForce 8800 Ultra have 128 stream processors and 24 ROP. In short, NVIDIA does not increase the number of unities and also does not touch the memory interface , always fixed at 384 bits, with memory volume 768 MB....
Whereas current GeForce 8800 GTX have the A02 G80 revision, The GeForce 8800 Ultra got the A03 version. The technical process remain the same as before 90nm, just like the number of transistors which is around the 680 million, But here nvidia was able to lower the power consumption of this new chip version.
NVIDIA announces then a maximum consumption of 175 Watts against 177 Watts for GeForce 8800 GTX. In the facts, we were not able to validate this power consumption, since according to our measurements, the card consumes a little more than the 8800 GTX:
Power consumption Overall System
GeForce 8800 GTX
GeForce 8800 GTX OC Asus
GeForce 8800 GTX OC eVGA
GeForce 8800 Ultra
Radeon X1950 XTX
Let us finish by referring the operation frequencies . The GeForce 8800 GTX operates at 575 MHz, the GeForce 8800 Ultra work at 612 MHz. On GeForce 8800 GTX, the shaders unities work @ 1350 MHz, While for the ultra version this frequency was increased to 1500 MHz . Side Memory frequency Nvidia finally pass from 900 MHz, with the GeForce 8800 GTX, to 1080 MHz on GeForce 8800 Ultra. The memory band-width was increased then from 86,4 Gb/S to 101,3 Gb/S.
Ultra GeForce 8800:
Taking again the black GeForce 8800 GTX PCB , and adopting the format PCI-Express 16x, The GeForce 8800 Ultra has identical dimensions as the GTX : 27 centimetres. the card has a dual slot cooler . The cooper base is connected with heat-pipe to the radiator. We note that the new fan in the 8800 Ultra is quieter than in the GTx Version. , a good point for NVIDIA.
Ultra GeForce 8800 NVIDIA
Equipped with two connectors SLI, the card has 768 Mb GDDR3 memory from Samsung . Naturally this case support HDCP . We have here two connectors DVI , connector mini-DIN for video out.
EVGA e-GeForce 8800 GTX ACS3
EVGA was one of the first to propose the overclocked version GeForce 8800 GTX in the form of e-GeForce 8800 GTX ACS3. Based on GeForce 8800 GTX, this card take again the black PCB GeForce 8800 GTX/Ultra and has 68 Mb video memory. The card was Supplied with two connectors PCI-Express (six pins). Identical to the GeForce 8800 GTX, the cooler here is dual slot with cooper base copper and heat pipe . The graphics chip work @ 626 MHz (against 575 MHz : standard frequency) whereas Stream processors work @ 1458 MHz (default version has 1350 MHz ). The memory frequency is set 1000 MHz , a little more than the 900 MHz normally recommended by NVIDIA.
GeForce 8800 GTX EVGA: e-GeForce 8800 GTX ACS 3 version
The card proposes two connectors DVI and a connector mini-DIN . We note that this card is not delivered with any game ! the GeForce 8800 GTX ACS3 is just delivered with driver CD , a manual without forgetting cables and other adapters.
Asus EN8800GTX Aquatank
Last January, Asus announced the GeForce 8800 GTX overclocked version : EN8800GTX Aquatank. This card as its clear from the name is water cooled , using in this case a water cooling system from ThermalTake. First obvious problem: the unit does not occupy two slots but four slots in your case! With its green PCB (and not black like other card ), the card has two power connectors .
Asus EN8800 GTX Aquatank
The Core frequency is set to 630 MHz whereas the stream processors was @ 1458 MHz. The 768 Mb GDDR3 memory operate at 1030 MHz. The asus card offers two ports DVI and a connector minis-DVI . Let us finish by the bundle which contains, in addition to driver CD , manuals and other cables , the game Ghost Recon and software 3DMark 06 complete version.
To test the performances of both GeForce 8800 GTX overclocked and GeForce 8800 Ultra, we used the following configuration :
Asus P5W-DH Deluxe - BIOS 1901,
Processor INTEL Core 2 X6800 Extreme - 2.93 GHz,
2x 1 Gb memory DDR2 Corsair Twin2X 6400C3,
Hard disk Western DIGITAL Raptor 150 Gb Serial-ATA 150
Our test machine operated under Windows Vista Edition ultimate with the last driver and BIOS available to the test date . For NVIDIA card we used the driver ForceWare 158.18 and CATALYST 7.4 for ATI cards .
3DMark 06 - v1.1.0
We start our tests serie with 3DMark 06. First note , our two GeForce 8800 GTX are with equality whereas GeForce 8800 Ultra show a small advantage above these two cards. Compared with reference GeForce 8800 GTX , the GeForce 8800 Ultra is 9% faster . NVIDIA offers large performance the ATI X1950 XTX is slower by 87%.
Doom 3 - v1.3
This game was always favorable to NVIDIA cards , those being largely at the head. The GeForce 8800 Ultra is more than 2 time faster than ATI Radeon X1950 XTX in 2560x1600. We note here that the overclocked GeForce 8800 GTX are very close and display similar performances to the GeForce 8800 Ultra. The GeForce 8800 GTX (reference ) is slower here by 10% than the ultra version.
Far Cry v1.4
We passes to Far Cry now. This game was tested with patch 1.4, without HDR, this function refuse to work under Windows Vista. Here, again the GeForce 8 is largely in front of the ATI Radeon X1950 XTX . the GeForce 8800 Ultra is 2% faster than the overclocked GeForce 8800 GTX and vs GeForce 8800 GTX standard , the last NVIDIA card is 11% faster .
F.E.A.R. - v1.08
F.E.A.R. confirms the preceding observations by classifying Asus GeForce 8800 GTX Aquatank with equality with the EVGA e-GeForce 8800 GTX and also with GeForce 8800. If Ultra .We note that in 1920x1200, the GeForce 8800 Ultra is 8% faster than the reference GeForce 8800 GTX , and 10% faster in 2560x1600. The GeForce 8800 ultra still twice faster than the Radeon X1950 XTX .
Splinter Cell Chaos Theory v1.05
The GeForce 8800 Ultra is in the first place in first being slightly faster than the overclocked GeForce 8800 GTX, whose performances are almost identical. The GeForce 8800 Ultra is 57% faster than the GeForce 8800 GTS 640 and 12% faster than reference GeForce 8800 GTX . The Radeon X1950 XTX remain twice slower ....
Half-Life 2 Lost Coast
The first position are always composed by GeForce 8800 Ultra and the overclocked 8800 GTX. But here the EVGA card is slightly faster than the GeForce 8800 Ultra, about additional 2 fps . Compared with standard GeForce 8800 GTX, the GeForce 8800 Ultra is only 5% faster . But vs Radeon X1950 XTX, the last card from NVIDIA is quite simply twice faster.
Call Of Dutty 2 - v1.3
For the first time Radeon X1950 XTX manages to do better than GeForce 8800 GTS 640 Mb and this in all Resolutions! But this is insufficient to reach the GeForce 8800 Ultra level which remains 41% faster . We note that in 1920x1200, the overclocked cards are faster than the 8800 Ultra . the GeForce 8800 ultra is 45 % faster than the GeForce 8800 GTS 640 Mb, and 9% faster than the standard GeForce 8800 GTX .
Compared with GeForce 8800 GTS 640, the GeForce 8800 Ultra is 54% faster whereas it is provide 84% higher performances than the ati Radeon X1950 XTX .
Company Of Heroes - v1.05
Company Of Heroes was in favor of GeForce 8. the GeForce 8800 Ultra is once again at the head, with a small boost over our two overclocked GeForce 8800 GTX witch show identical performances .The GeForce 8800 Ultra is 63% faster than GeForce 8800 GTS 640 MB and 86% faster than the Radeon X1950 XTX.
Without surprise we finds at the head and with almost perfect equality our three GeForce 8800 Ultra and overclocked GTX. Vs the basic GeForce 8800 GTX, these cards offer an average gain of 9% and 51% over the GeForce 8800 GTS 640 Mb. The ATI Radeon X1950 XTX completely fail in this test…
Doom 3 - v1.3 - AA 4x
Here we activate anti-aliasing 4x . The GeForce 8800 Ultra preserve a very light boost over both overclocked GeForce 8800 GTX from Asus and EVGA . Compared to GeForce standard 8800 GTX, the new GeForce 8800 Ultra appears to be 12% faster.
Call Of Duty 2 - v1.3 - AA 4x & AF
Here various filtering options was activated , Call Off Duty 2 draws up a panorama rather similar to that observed until now about the performances of our cards. . This game was in favor of Radeon X1950 XTX, in this test the ati card was able to compete with GeForce 8800 GTS 640 Mb in the lowest Resolutions.
F.E.A.R. v1.08 - AA 4x - AF16x
The activation of filtering options under F.E.A.R. hardly seems to limit NVIDIA cards . Those are largely faster than Radeon X1950 XTX which was able to be as fast as a GeForce 8800 GTS 640 in 2560x1600. In the highest Resolution, the 8800 Ultra is 4% faster than our best 8800 GTX (Asus). Vs GeForce 8800 GTX, the ultra version is 18% faster .
Half Life 2 Lost Coast - AA4x - AF16x
The activation of anti-aliasing 4x and anisotropic filtering 16x in Half-Life 2 allow the Radeon X1950 XTX to catch the GeForce 8800 GTS 640 Mb, but this last still 33% faster ..
Extremely powerful three cards was tested today . We note that the large delays with the release of R600 allow NVIDIA to get the hole high end video card category .
As for the new GeForce 8800 Ultra proposes to us today, its performances is slightly higher than our two overclocked models. Vs the standard GeForce 8800 GTX, the Ultra version is 9% faster under 3DMark 06, which is not exceptional. Then why NVIDIA does it launch this new card? Probably to increase its advantage over the future R600 whose performances would not be able to worry current GeForce 8800 GTX. ....
