7900GS REVIEW LEADTEK WINFAST PX7900GS TDH VS 7900GT AND X1900GT BENCHMARK AND OVERCLOCKING By :pc hardware news Posted:2006-09-06 xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source while waiting to the launch of G80, the first graphics chip DirectX 10, NVIDIA return to us with GeForce 7900 GS . Already available for some time with the PC manufacturers  , GeForce 7900 GS make today its appearance in box version .. With GeForce 7900 GS, NVIDIA supplement its range and   propose a competitive chip for each budget. GeForce 7900 GS: the chip, characteristics the chip have only one additional variation  from the  G71 which equips already GeForce 7900 gt and 7900 GTX. Thus heriting the architecture of GeForce 7, the GeForce 7900 GS is a graphics chip of class DirectX 9.0c, compatible with Shader Model 3.0.  thus we finds there  HDR , antialiasing  transparency t...support . made in 90 Nm it count 278 million transistors, GeForce 7900 GS counts only 20 pixels pipelines, when the other members of the family GeForce 7900, like GeForce 7900 gt & GTX, hase 24 of them. due to  this reduction in the number of pixels pipelines, the number of  vertex  units was also  re-examined thery 7. As regards to these unit,the ROP located in end of pipeline  manage certain tasks  like the antialiasing, one counts 16 of them  in the GeForce 7900 GS. Like other G71 card, GeForce 7900 GS  without surprise has 256 bits memory bus   and use GDDR3 memory. Its frequencies  are 450 MHz for the graphics chip, the units in load of the Vertexes operating slightly more higher with 470 MHz, whereas the memory is working at 660 MHz, as on GeForce 7900 gt.  let us recall that the chip support technology SLI and benefits from the PureVideo engine  type MPEG 2, WMV9 or H.264. In premium, NVIDIA proposes the management  Dual-Link DVI what allows to controle  two screens 30 inches using only one card.

Whereas GeForce 7800 gt measures about 21,5 cm length, the small last does not exceed 19 cm. With type PCI-Express  16x, WinFast is equipped with a connector for a secondary power supply contrary to GeForce 7600 GT. Side cooling system  , Leadtek was made the cooler  using NVIDIA reference. We are  in the presence of a metal radiator covering at the same time the memories chips  and the graphics chip. Provided with 256 Mb of memory GDDR3, the card uses Hynix certified with 1,4 NS and working at 660 MHz. the Samsung chips are usually equipping the GeForce 7900 gt and those certainly cost higher… Respecting the specifications of NVIDIA, WinFast PX7900GS TDH leave its graphics processor at 450 MHz.  in addition  Leadtek also proposes with its catalog WinFast PX7900GS TDH Extreme. This one has   higher  GPU frequencies working at 520 MHz.  this last  also use chips Hynix memories with 1,4ns, and 256 Mb of memory at 700 MHz. GeForce 7900 GS  Leadtek: WinFast PX7900GS TDH With two connectors DVI , the card also offers an exit mini-DIN for the video. Equipped with a strip SLI, PX7900GS TDH  Leadtek  in addition provide  the additional chip necessary to the  HDCP. Question bundle, the manufacturer delivers only one adapter DVI/VGA, a  Molex cable as well as a connector with the video out in component and S-Video. in addition we finds the usual books and driver CD  and some software such Cyberlink PowerDVD 6  . Leadtek does not forget gamer  and delivers two game: SpellForce 2 Shadow Wars and Trackmania Nations. To test the performances of the GeForce 7900 GS we had used to the following configuration: MotherBoard Asus P5N32 SE SLI Deluxe, Processor INTEL Core 2 Extreme 6800, 2x1 G Corsair Twin2X 6400C3, Hard disk Western DIGITAL Raptor 150 Go Serial-ATA 150 Our machine was provided with Windows XP Professionnel Service Pack 2 and with the last driver ForceWare 91.47. On this platform, we could test the performances of following  NVIDIA card: GeForce 7600 GT, GeForce 7800 GT, GeForce 7900 GT in addition to GeForce 7900 GS  in mode SLI. We have not forget  ATI  card and while waiting for the Radeon X1950 Pro we used the Radeon X1800 GTO and Radeon X1900GT, tested on the following platform: Motherboard Asus P5W-DH Deluxe, Processor INTEL Core 2 Extreme 6800, 2x1 G Corsair Twin2X 6400C3, Hard disk Western DIGITAL Raptor 150 Go Serial-ATA 150 we used the CATALYST 6.8. On   NVIDIA driver we activate the adjustment “higher Quality” whereas on  ATI driver we use the option “AF  quality”. 3DMark 06 we starts with great classic3DMark 06.  The SLI of GeForce 7900 GS is logically at the head and the new NVIDIA reference   rises between GeForce 7800 gt and GeForce 7900 gt. As for Radeon X1900 gt it just take  the second place in all the resolution. Quake 4 - v1.2 Thanks to last version 6.8  CATALYST the performances of ATI chips  under Quake 4 appreciably improved. Result that the Radeon X1900 gt preserves its second position while GeForce 7900 GS does very slightly better than Radeon X1800 GTO. Compared with GeForce 7600 gt,the GeForce 7900 GS is here faster by 34% in 1600x1200! Tomb Raider Legends v1.2 Tested here using FRAPS, lara croft seems to give a  beautiful boost of NVIDIA chips . The SLI  GeForce 7900 GS is logically at the head and offers a profit of performances by about  29% compared to the performances of GeForce 7900 GS alone. The card from Leadtek  shown here 12% better performanc  than the GeForce 7800 gt but this is not enough to precede the Radeon X1900 gt which was placed  in third position right after the GeForce 7900 gt. This last preserves an advantage of 12% aver the GeForce 7900 GS in 1600x1200. Half-Life 2 - Lost Coast The SLI  still the best solution to obtain optimal performances. GeForce 7900 GT arrives here in second position followed by the Radeon X1900 gt .the GeForce 7900 GS is very close with its direct rival the Radeon X1900 gt..as for 7900gs vs GeForce 7600 gt, the card from Leadtek is faster by 36% .. Far Cry v1.4 Beta - HDR This time  we use the patch 1.4 which still  in version beta makes  possible to activate the effects HDR   on ATI chips . Result : the GeForce 7900 GS is with equality with Radeon X1900 gt whereas GeForce 7900 gt precedes them by a little . Radeon X1800 GTO makes red figure  particularly in 1600x1200, whereas GeForce 7900 GS proves to be13% more powerful than the GeForce 7800 gt. Lastly, to pass from GeForce 7900 GS with two GeForce 7900 GS in SLI increase the performances has about   79% ! Splinter Concealment Theory Chaos - v1.05 For Sam Fisher, GeForce 7900 GT remains the fastest card, the Radeon X1900 gt  finishes third. The last born of NVIDIA finishes just behind the chip of ATI, whereas the SLI is  the leader. The advantage of Radeon X1900 gt on GeForce 7900 GS reaches 6% here. F.E.A.R. v1.07 Released   recently, version 1.07 of F.E.A.R. gives  favors to chips NVIDIA with GeForce 7900 GS which precedes Radeon X1900 gt. The first cards return with the SLI of GeForce 7900 GS and GeForce 7900 gt. This one preserves an advantage of 10% over the GeForce 7900 GS in 1600x1200, whereas here the Radeon X1800 GTO show poor performance. Need For Speed Most Wanted - v1.03 Need For Speed gives its preference to GeForce 7900 GS which shows 8% faster performance than Radeon X1900 gt. Naturally GeForce 7900 gt preserves a beautiful advantage over the card from Leadtek, in particular thanks to its four pixels additional pipelines. GeForce 7900 GS  Vs GeForce 7600 gt, result in 40% more fps! Cal Off Duty 2 - v1.3 OThe Radeon X1900 GT posts here   beautiful performances to exceed our GeForce 7900 GS but also GeForce 7900 gt! GeForce 7900 gt is 9% faster  than GeForce 7900 GS, and the Radeon X1900 gt shows 31% better performance in1600x1200! Cal Off Duty 2 - v1.3 - AA4x & AF The activation of filtering functions of filtering give pretty the same result. the Radeon gt WP is faster by 14%  than the GeForce 7900 GS. This last  become close with it s  big brother GeForce 7900 gt. Once again the performances difference   between GeForce 7600 gt and GeForce 7900 GS exceeds the 30%  here with variation of 35% in 1600x1200. F.E.A.R. - V1.07 - FSAA 4X + AF 8X For F.E.A.R. the  filtering option gives give  light advantage to the Radeon X1900 gt vs GeForce 7900 GS. Unfortunately for ATI, Radeon X1900 gt is with equality with GeForce 7900 gt . passing from one GeForce 7900 GS to two GeForce 7900 GS in SLI increase  the performances level by 90%! Quake 4 v1.2 - FSAA 4x The activation of antialiasing under Quake 4 was very favorable to ATI chips . The Radeon X1800 GTO which hardly get it s place until now goes up in the third place!whereas the SLI  GeForce 7900 GS remains the leader .the GeForce 7900 GT show simlar performances  with the GeForce 7900 GS: not more than 4%  difference between them! Half-Life 2 Lost Coast - FSAA 4x + AF8x Under Half-Life 2 GeForces take again their rights and GeForce 7900 gt finishes second. The Radeon X1900 gt  precedes the GeForce 7900 GS but by a little:  " 6% ". GeForce 7900 GS   vs GeForce 7600 gt result with  higher 41% performances  in 1600x1200. 7900 gs Overclocking Question overclocking, our WinFast PX7900GS TDH showed good result! We could  easily increase the GPU from the default of 450 MHz  to 535 MHz. .the memory Chips 1,4 go at 700 MHz . Result: 9%  higher performances under Quake 4.the overclocking result is pretty logical since those card should overclock the same or better than the 7900gt 7900gs Conclusion The GeForce 7900 GS makes  possible for NVIDIA to  offer  graphics chips  filling between the GeForce 7600 gt and GeForce 7900 gt. Let us recall  that the GeForce 7600 gt is negotiated on average of  160 euros, when it is necessary tusers spend 100 euros more for   higher model as the GeForce 7900 gt. GeForce 7900 GS thus positions as an intermediate product witch price is fixed at 219 euro. The performances of the GeForce 7900 GS is completely a bit lower than the GeForce 7900 gt, but better than GeForce 7800 gt. Compared with GeForce 7600 gt, this card have  higher performances with about 30%! GeForce 7900 GS very often lose over the Radeon X1900 gt which is proposed with same price. if it is necessary to make a choice between Radeon X1900 gt and GeForce 7900 GS we would choose all the way the ati card which in addition to its  good performances generally offers higher image quality and allows the activation of antialiasing when the effects  HDR are used, witch is impossible thing at NVIDIA. xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source we would be happy to answer for your question . if you have suggestion or comment regarding this review our support would be glad to help just join our forum and ask u will get the best answer to discuss check our forum section :-) RATE THIS REVIEW 1 2 3 4 5    / 5   View Stat
