NVIDIA 7900 GT / GTX DRIVER SPEED COMPARISON CHART : 7900GT BEST DRIVER ,OVECLOCKING ,VOLT MOD AND MUCH MORE By :video card Posted:2006-08-07 xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source well I was browsing the net today and found that in eatch forum the same question is asked what is the best driver to use for my g71 card 7900gt / 7900gtx. the answer was alwais the lastest one.this was the main reason for writing this review.we have done a driver performance chart for the 7900gt card and tested the driver using difrent test and benchmark. as u know the 7900gt card is one of the best card availble those day .the card is cheaper than the 7900gtx and offer good performance in all today game.here is 7900gt card specification.   Geforce 7900 GT Geforce 7900 GTX Graphics Bus Technology PCI Express PCI Express Memory 256 MB / 512 MB 512 MB Memory Bandwidth (GB/sec) 41.4* 51.2 Memory Interface 256-bit 256-bit Fill Rate (Billion pixels/sec) 10.8 * 15.6 Pixels per clock (peak) 24 24 Gpu clock 450 * MHz  650 MHz memory clock 1320 *  MHz 1600 MHz * : Those value depond from manufuculter and video card versions.some 7900gt  card are preoverclocked and have higher MHz value.the card tested today is asus 7900gt 256 mb witch have 450 MHz core / 1320 MHz  memory - As u can see the main difference between the cards 7900gt / gtx is the working clock frequency and for some card the additional  256 mb memory.lets remind 1) that the 7900gtx has 1.2 nano second memory and the 7900gt has 1.4 only witch correspond to 1400 mhz. 2) the 7900gtx has 512 mb memory and the 7900gt has usualy 256mb. 3) the cooling core / memory cooling used in the 7900gtx is a lot better than the one in 7900 gt 4) and last the most importatnt to us is the core working vcore .the 7900 gtx work with 1.4 v core and the 7900 gt has 1.2 only. so basiquely if we crank the 7900gt vcore to 1.4 we should get the 650 MHz in the core :-) . the v core mod Can be done very easily with a conductive pen, connecting those 2 points by the yellow line. It will boost the voltage to 1.4v from the original 1.2v, giving it the same potiential as a GTX. Many have reached GTX speeds and beyond by doing this mod. we sould return to the overclocking later on this review. here is how we tested the drivers.we had started with clean widows xp sp2 installation .then installed all driver except the graphic driver one.and finally we made ghost back up to assure the reability of result.after eatch driver installation and tests we just restored the system to previews stats using the original back up image. System used : Cpu: Amd athlon 64 FX 55 (2600mhz with 1 mb cache). Motherboard : A8N-SLI Premium using the lastest bios . Memory : 2 * 1 Gig corsair pc-4000 working @ DDR 4000 5-3-3-2 T default setting. Hdd : 2 * WD raptor 74 gig in raid 0 configuration. Psu : forton 550 w Video card : asus 7900 gt 450 /1320 default clock * all driver setting was set default : Antialiasing          application controlled Anisotropic filtering    application controlled Image settings   Quality Vertical sync         application controlled Force mipmaps          none Conformant texture clamp      on Extension Limit       off Anisotropic mip filter optimization off Anisotropic sample optimization on gama correct Antialiasing    off transparency antialiasing    off Triple buffering   off Negative lod bia        allow * Note:Some Tweaked driver come with different setting we changed them manualy to match the one abrove. we had tried to use the 8x.xx generation and the 9x.xx generation for better result so we picked up different driver from those family .we also added some modded driver such as Z-Tweaked nvidia driver and nvodngov.and for sure some beta and whql driver from nvidia Now here is the List of driver used : 1)  84.21 whql verified 2)  84.26 whql verified 3)  nVidia Forceware 85.13 4)  nVidia Forceware 85.96 5)  nVidia Forceware 85.98 6)  Z-Tweaked v87.2 7)  Z-Tweaked v9128 8)  nvodngov  9131 9)  91.31 whql verified lastest driver availble from nvidia site . 10) 91.37 lastest beta version availble : note we used a modded inf to get this driver working .the 91.37 is for 7950 gx 2 only  at the moment . all those driver are avaible in guru3d.com . good lack with your download  :- ). benchmark software and 3 d mark series : 3d mark 2001 7900 gt driver performance chart as a start the good old 3d mark 2001 benchmark test . 3d mark 2001 is full system test it is based on graphic performance only so the result gotten is about the overall system performance. The z- tweaked drivers are showing the best result wile the 85.96 is completely failling in this test . there should be some tweak applied in the mipmaps  bias level in those tweaked driver.generally speaking the 80 serie and 90 nvidia serie showed similar performance .the 9x.xx driver take slightly the lead over the non tweaked 8x.xx one.in any case this test show the overall system performance it is not graphic card based lets move to the 3d mark  2003 test witch more video card hungry 3d mark 2003 7900 gt driver performance chart the figure abrove repeat it self agin the z-tweaked driver version 87.25 showing the highest performance.the 8x.xx serie are better performer than the 9x.xx driver in this test here is the detailed test result The first test in 3d 2003 " wings of fury " all the driver show pretty similar performance .except for the z- tweaked 87.25 driver witch completely failling in this test.but wait this driver is the overall winner .strange lets check the next test for more expliquation. the z- tweaked 87.25 driver become the leader here the lastest nvidia whql driver "91.31" show poor performance here the next waited beta version show better result but still a lot of work to do here lets hope that nvidia will fix the poor performance here. again the z- tweaked 87.25 is the leader in this test. generaly this driver serie are taking the lead in eatch test, while the nvodngov driver are showing a slightly better performance than the 91.31 whql driver. finally the lastest test and the hardest one in this serie.the 9x.xx driver are showing similar performance worse than the 8x.xx driver except for the z-tweaked one witch still showing great result. 3d mark 2005 7900 gt driver performance chart here is the another test from 3d mark serie witch 100% video card hungry. the mark abrove show the overall video card performance using different driver. as in the 2003 test the 8x.xx serie perform better than the 9x.xx.here is the detailled 3d 2005 benchmark result lol : here it is become clear why the performance of the z-tweaked driver are so high. no need for screen shot to check the image quality :-).it is clear that this driver have the wrost quality here here has an inexpected performance boost with 85.98 driver .we had runned the test twice to confirm the result and yes 10 fps boost without image quality lost . I wonder why nvidia d not use this tipe in their future driver.maybe there was some hidden tweak with this driver version for this test. the 8x.xx driver continue showing  better result than the 9x.xx one. 3d mark 2006 7900 gt driver performance chart witch good known 7900gt failure in the deep freeze test we decided to loop this test and check the card temp using different driver version . the test was repeated 4 time than we marked the highest tempurature.we highly recommand to anyone buying 7900gt card to loop this test for 12 hours and check the card from defect.there was huge of card retruning due to freeze or crippled texture in this test most of them where from Evga. Deep freeze temp serie :  84.21 whql verified            84.26 whql verified          nVidia Forceware 85.13                        nVidia Forceware 85.96  nVidia Forceware 85.98    Z-Tweaked v87.2                          Z-Tweaked v9128                    nvodngov  9131              91.31 whql                        91.37 beta all the driver showed pretty similar temp in the test max temp recorded was about 68c . except the lastest beta from nvidia " 91.37 beta" witch show 2c higher than all other driver with 70c load here is the result from 3d mark 2006 test. remenber that in the 3dmark 2006 serie the cpu score count.the fx 55 is scoring about 1000 mark in this test .this test support dual core so u should get twince higher score with an fx 60 (dual core processor with 2 * 2600 MHz 1 mb eatch one cache).: The 3DMark Score is calculated using the following formula: SM2.0 Score = 120 x 0.5 x (SM2 GT1 fps + SM2 GT2 fps) HDR/SM3.0 Score = 100 x 0.5 x (SM3 GT1 fps + SM3 GT2 fps) CPU Score = 2500 x Sqrt( CPU1 fps x CPU2 fps) generaly speaking the 8x.xx serie still better in all 3 dmark serie test the lastest beta from nvidia do not show any improvement over the current realise it pretty clear that the new beta will contain sli and quad sli support and dedicated for multigpu configuration. here is the test result it is clear now witch driver should I use when benching :-). for many gamer benchmark still benchmark and do not reflect the real gaming experience so we added some game test to the chart list. battlefield 2 7900gt driver chart The test was done using fraps. to calculate the max min and average frame rate.the number in red color are showing the average one.the setting used in 1024*768 with all setting to and 4x aa.all the driver in performance language are pretty similar no one offer a nice boost. the 84.21 whql driver has the lowest fps recorded.all the driver offer good frame rate at this resolution. FEAR 2 7900gt driver chart For FEAR test we used the test configuration to get the max min and average frame rate the resolution was set the 1280/960 with max setting (4AA-16AF) with soft shadow enabled. AA : Antialiasing          AF : Anisotropic filtering   . the 8x.xx offer better game play with 2 fps higher frame rate.the z-tweaked 87.25 still flying but at the cost of performance. Oblivion 2 7900gt driver chart the most graphic hungry game those day .especially the oudoor where we tested . we recorded the frame rate using fraps.the setting was 1280/1024 all graphic setting  to max with HDR enabled .the 7900gt was not able to handle such resolution .here we can see the boost of 9x.xx driver over the old one.nvidia has worked to improve the performance of newer driver in this game.so if u are looking to play oblivion go with 9x.xx driver serie. Need for Speed Most Wanted 7900gt driver chart Setting used in the test was recording frame rate using fraps. 1600/1200 resolution all graphic detail to max setting one of my favorite game :-) .the 9x.xx loose the lead again over the older driver.the tweaked driver show the best performance in this game.the frame rate was enough to allow game play with such resoltion and setting all the driver performed over the 25 fps range Quake 4 7900gt driver chart Nvidia is know with their pretty well optimized oven gl driver.we started by recording our oun demo then crancked the resolution up to 1600/1200 with (16AA-4AF).the result was poor performance using all driver the game is not playble with such setting.the most inportant fact that the 8x.xx serie are better performer in opengl application than the 9x.xx one.note also that all tweaked driver are also failing in this test Far Cry 7900gt driver chart the game is getting older and older but we sould agree that this game is best graphic game intll today.the benchmark was done using the benchmark of " \map pier " then " \demo 1 " .the resolution was set 1600/1200 all setting set to max with hdr enabled and set to 11 .note:to enable hdr in far cry u should have the 1.3 patch or higher the "~" to open console the type : " \r_hdrrendering x " x: is number in our test wes set to 11.the same figure the 8x.xx driver are better performer in this game . 7900 gt oveclocking using coolbit v 2: we used cool bit then the auto detect future in all driver to see how much the overclocking result varie.here is the clock chart gotten Note: The card test is already voltmoded to 1.4 v this should explique the high gpu clock. From personnal test the card is capable of 670 MHz /1800 MHz (900 MHz ) and stably work .tested with ati tool for over 2 hours without artifact.it s look that there is a kind of limit in the memory overclocking in the autodetect future it show alwais the max of 784 and could not go higher between when we set the memory clock to 800 for exemple and press the test button the result would be test passed.so this is nvidia overclocking protection with cool bit future no more than 784 MHz is expected.u should already noted the low overclock using the 85.13 driver version :this should be expliquated as the fellow : there was only the new nvidia control pannel  and the cool bit auto detect future alwais show lower result using this pannel here some intersing fact during the 3 day review :-) using the 85.98 driver there was a nice new option : using the 84.21 driver : pc  hang up wile executing \ exit far cry .such command is not supported by this driver : - ). using the 87 z tweaked driver : the game menu in battlefield 2 is crippled. I can barrely see anything using the lastest nvidia driver 91.31 : first the message : while I am not using sli configuration and second playing 1.6 conter strike look to the screen shot : . u can see the black square in the screen . note: those issue already fixed in the lastest beta version.. now time to some overclocking :-) . 7900gt overclock 3dmark 2003 7900gt overclocked result 3dmark 2005 7900gt overclocked result 3dmark 2006 7900gt overclocked result 7900gt gaming result Fear performance Far cry performance Nfs Most wanted performance from all previous result u can see that the overclock give the card nice performance boost.from 20.to 25% boost the frame rate become a lot .better. Conclution: No driver is perfect .it offer good performance is  in one game and fail in other.the 8x.xx driver showed better overall performance than the 9x.xx. I cant go wrong with lastest version I don\'t play cs 1.6 :-).   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
