VIDEO CARD POWER REQUIREMENT REVIEW : X1900XTX 7900GTX 7900GT 7600GT X1600XT X1300 7600GS .. By :power Posted:2006-07-31 xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source it is true that new graphc card get more powerful they require better psu "power supply quality" due to the more power requirement and and better cooling.more power mean more heats and more cooling .cuurent video card require powerfull fan witch should increase the noise level.the noise come to critical level when we talk performance cooling noise ratio.today we should look for deferent video card high and middle end range to find out witch card performe better with lowest power and noise level ". we had used a digital multimetre to measure different power line and idle and load to find out the power requirement for those modern cards: the sustem used : CPU: Intel Pentium 4 560 CPU (3.60GHz, 1MB L2) MOtherboard: Intel Desktop Board D925XCV Memory: PC-4300 DDR2 SDRAM (2x512MB) Hard drive: Samsung SpinPoint SP1213C HDD (Serial ATA-150, 8MB buffer) operating system :Microsoft Windows XP Pro SP2, DirectX 9.0c. Driver ATI Catalyst 6.6, Nvidia ForceWare 84.21 According to the PCI Express x16  specification it can transfer  up to 72 watts  through the +12V lines  through the mainboard and to get the additional the power connector is required for exmple to get 144 watts in total. The 3d peak load was done using the first sm3.0 test of 3dmark 2006 then we run this test in loop at 1600x1200 resolution with 4aa and 16 af (aa:antialiasing  ; af:anisotropic filtering). to get the 2d peak load we used pc mark 2005 test "the transparent windows" modern video card Noise Level AMD Athlon 64 FX-60 CPU with Zalman CNPS9500 cooler working at its minimum rotation speed. Asus A8N32-SLI Deluxe mainboard (nForce4 SLI X16) for Nvidia GeForce graphics cards Asus A8R32-MVP Deluxe mainboard (ATI CrossFire Xpress 3200) for ATI Radeon graphics cards OCZ PC-3200 Platinum EL DDR SDRAM (2x1GB, CL2-3-2-5) Maxtor MaXLine III 7B250S0 HDD (Serial ATA-150, 16MB buffer) Enermax Liberty 620W PSU (ELT620AWT, 620W) Microsoft Windows XP Pro SP2, DirectX 9.0c ATI Catalyst 6.6, Nvidia ForceWare 84.21 modern video card Power Consumption The 7950gx2 work on the 7900gt frequency witch consume about 48w so basiquely it should note require more than 100-120 w .we could not test this card because it require certified motherbaord so data just been writen from nvidia specification. . as u can see the 7900gtx has more optimized power consumption it architecture contain less transistor.this should explique the 33% lower power under max 3d load When idle or under high 2D load, both the top-end graphics cards from ATI and Nvidia need almost the same amount of power. under 3d peak the radeon x1900xtx becaume a power hungry and it consume the same 45 w from the moterboard power circuitry Noise Level this diagram show that cooler used on those card had about 45 DBA in 2 d mode.note:that the geforce gx2 has more quieter cooler than all other product.but as soon as 3d appalication launch it becaume noisy.the fan used in the 7900gtx remain quite in any case (3d or 2d regime ).the x1900xtx has also a noisy fan. those value are acceptable since the 7900gtx consume less power --> less heat --> less noise High-End Graphics Cards ATI Radeon X1900 XT ATI Radeon X1900 GT ATI Radeon X1800 XT Nvidia GeForce 7900 GT Those card have the acutal price range from 250 to 400$ deponding from manufacturer.as u know the the most expensive did not mean the fastest.those card present rowlly the same performance in the overall.so the buyer choice could be based on specifique game performance. from the price list u can find that the radeon x1900xt and the x1900gt are the most expensice they come with dual slot cooler.the 7900gtx come with smaller cooler. Power Consumption well as u see the power winner is the geforce 7900gt .note that the main difrence between the 7900gtx and the 7900gt in the voltage applied to the core during the 3d mode.the 7900gtx has 1.4v vs 1.2v for the 7900gt so basiquely if u vmode the 7900gt to 1.4v u should get the 650mhz in the gpu.the other two diference are the memory size and memory chip. the 7900gtx come with 512 mb on board memory 1.1ns the 7900gt has 256 mb and 1.4 ns the 7900gt show as vA very economical solution it eat almost twice lower power than all other video card, Noise Level as already was showin with power the 7900gt is the quietest here.the x1900xt and radeon x1800xt has identical cooler witch produce the same noise ammount (45 dba) Performance-Mainstream Graphics Cards ATI Radeon X1800 XL ATI Radeon X1800 GTO Nvidia GeForce 7600 GT Thiose card already support dual dvi output .except fro the 7600gt only one so u can plug large monitor using them Power Consumption the nvidia solution show better power management even in the Mainstream graphic cards TThe less power can be easy expliquated in this case the 7600gt use only 177 million of transistor vs 320 million for the x1800gto witch is twice higher. so the result is pretty logic.50w for video card in load is far to be a lot is our day .note that future video card from nvidia and radeon with direct x support are with 150 to 300w range with almost 6 time more .the x1800gto has an avantage here this is the 256 bit memory bus witch will help a lot in high resoltuion when aa and af are enabled Noise Level is opposite to the geforce 7900gt the 7600 gt ahs fan witch regulated depending from current GPU temperature.so as soon as the 700gt gpu reach certain temperature the noise becaume higher.there is two difrent cooling system used in the radeon x1800xl and the radeon x1800gto . first one: small diamter witch lourder when fan speed grow up second one:larger with lower fan speed and noise level. those cooler varie deponding from manuficture Mainstream Graphics Cards ATI Radeon X1600 XT ATI Radeon X1600 Pro Nvidia GeForce 7600 GS* Nvidia GeForce 6600 GT now we come to the price range of 99 to 200$ cards.such video cards present similar performance   Power Consumption the 6600gt has the highest power requirement here this due to that the card was built in old architecture if we take a look to 7600gs witch present better performance we can see the low power for the geforce 7 based card 27 w only .any psu should handle the load form such card The 90nm GeForce 7600 GS boasts the lowest power draw at 27W. The Radeon X1600 cards need the same amount of power, a little more than their opponent requires. Although the Radeon X1600 Pro has lower frequencies than the Radeon X1600 XT, it uses power-hungry GDDR2 memory and works at the same voltage, so as a result it requires as much power as the senior model in the series. Noise Level the mojority of 7600gs come with passive cooling so we had nothink to messure :-).remmenber the 27 watt a passive cooling can be enough.the Radeon X1600 XT sample from ATI, it is the noisiest graphics card of all in this batch, because its cooling system always works at its maximum speed. Entry-Level Graphics Cards ATI Radeon X1300 Pro Nvidia GeForce 7300 GS S3 Graphics Chrome S27 Power Consumption the Nvidia GeForce 7300 GS. Despite the low performance and only 64-bit memory bus, this solution eats up less power than any of the graphics cards we have tested today. Noise Level Of course, the GeForce 7300 GS graphics card with the passive cooling cannot generate any noises.  for the Chrome S27, we can only mention the level of generated noise for this particular reference graphics card. It equals 45dBA, which hardly illustrates anything, because there are no products in the market at this time. 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
