HIS RADEON X1900 GT ICEQ3 REVIEW VS 7900GT OVERCLOCK PERFORMANCE AND BENCHMARK By :video card review Posted:2006-09-05 xtreview is your : Video card - cpu - memory - Hard drive - power supply unit source the GeForce 7900 gt have comparable performance with GeForce 7800 GTX and suggested with the price arround 300euro.It is true that the G71 is a particularly profitable chip made in 90 Nm  . NVIDIA  was able to reduce the number of transistors for their new card so they run cool and require less power… so  ATI answers the  GeForce 7900 gt with Radeon X1900 gt, kind of   Radeon X1900 XT. We opposed the HIS Radeon X1900 gt IceQ3 to GeForce 7900 gt in order to check if the response of ATI  was strong enough… 7900 gt spec overview GeForce 7900 gt is based on the known G71 derived from the year ago launched G70  . GeForce 7800 gt is made in 90 Nm against 110 Nm for the 7800 serie, which leads to a size of 196 mm ² instead of 332 mm ² for its predecessor. NVIDIA was succeeded to save 7.5% in the transistors ammunt: “only 278 million against 302 million but with identical performances at equal frequency. working at 450 MHz, the G71 of GeForce 7900 gt is 30 MHz faster than G70 of GeForce 7800 GTX.  Last detail, GeForce 7900 gt is satisfied with a relatively simple PCB and  HSF in other word the most economic.   ATi radeon x1900gt Nvidia Geforce 7900gt Chip R580 G71 tech Process 110nm 90nm Num of Transistors 384 milions 284 milions Surface 351 mm 196 mm Gpu Frequency 675 Mhz 450 MHz Memory Frequency 600 MHz 660 MHz Memory Bus 256 Bits 256 Bits Vertex engine 8 8 Pixel Pipeline 36 24 Texturing Units 12 24 Rops 12 16 Fillrate 20700 mp/s 10800 mp/s Geometry 1150 mv/s 936 mv/s Memory Brandwith 38 GIG/s 41 GIG/s x1900 gt spec overview To produce Radeon X1900 GT, ATI applies the same receipt as for Radeon X 1800 GTO. The chip used  here is R580 which preserves its 8 vertexes units but loosing a part of its pipelines . In practice, R580 takes ¼ here and preserves: 36 pixel shader pipelines, 12 texturing units and 12 ROP' S. Radeon X1900 GT is fortunately not  too much attached on the level of  frequency and the VPU is work at 575 MHz, which give him a frankly high geometrical power compared to its fillrate. X1900 GT has 256 MB memory working  at 600 MHz with 256 bits memory bus. Unfortunately for ATI, R580 remains a large chip and it  occupies 351 mm ² for its 384 million transistors. However, by taking the  ¾ pixel pipelines, Radeon X1900 gt makes  possible to ATI to run out R580 chip which  do not pass successfully the qualification tests   for the models X1900 XT and X1900 XTX. Moreover, its PCB is comparable with  the thigh-end-range models . in a word we had pretty simlar card .Nvidia use the 7900gt to produce video card witch are not capable to run at the 7900gtx speed : the 7900 gt run with 1.2 volt at 450 MHz the GTX at 1.35-.1.4v at 650 MHz so if the test show that the G71 chip could not run with 1.35 v at 650 MHz the card will becaume a 7900gt .the same do ati with their x1900gt but radeon here desable some pipeline before.this is only the theorical overview but in real life marketing have more effect .in some case where there is large demond for ex  7900 gt some manuficulter could sell the gtx gpu as gt and here overclocker come with nice result :-) HIS Radeon X1900 gt IceQ3 The IceQ models of HIS is equipped with quiet system   cooling made by Arctic Cooling. This last have already stopped  marking the ATI Silencer,so the model assembled on the Radeon X1900 gt is specific to HIS. It uses copper radiators fixed by  screws , this was not very practical to dismount! The radiator of the GPU is also made from copper . . The completion of the cooling system from HIS is exemplary, just for those who like silent operation. Under this cooler, we finds a good large R580 with  extremely large ammount of thermal paste and chips Samsung K4J55323QG-BC14 certified for 700 MHz. These chips are GDDR3 so we can predict a beautiful overclocking margin  . The bundle delivered by HIS is composed of two DVI adapters   - > VGA,  adapter HDTV, an adapter with video in/out S-VHS and finally a Molex adapter    . HIS also delivers nice game (Flat out) and Power DVD 6.0 as well as a CD-ROM with the driver and a second with utilities . Taking into account the cooling system  ,  asking the price of 330 € does not seem excessive… Configuration of test Sapphire A9RD580Adv and Asus A8N-SLI Premium AMD Athlon 64 X2 4200+ 2 X 512 MB DDR400 2226 HIS Radeon X1900 gt and NVIDIA GeForce 7900 gt Maxtor DiamondMax More 9.120Go SATA-150 ViewSonic VP171s Software Windows XP Pro + SP2 ForceWare 91.33 and Catalyst 6.6 Futuremark 3D Mark 2005 Futuremark 3D Mark 2006 Futuremark PC Mark 2006 Riddick EFBB 1280 X 1024 HQ SM2 FarCry 1280 X 1024 UQ Doom III 1280 X 1024 HQ TrackMania Sunrise 1280x1024 HQ Serious Sam 2 1280x1024 HQ Splinter Concealment CT 1280x1024 HQ SM3 F.E.A.R. 1280x1024 HQ 3dmark 2005  score 3dmark 2006  score Gaming benchmark no AA or AF First benchmark charts was done using the 1280x1024 resoltuion but without AA and AF     Gaming benchmark with AA and AF Second benchmark charts was done using the 1280x1024 resoltuion but with 4AA and 8AF On the  performance level, it is a disappointment from the x1900Gt. if th  Radeon X1800 GTO ca complete in comparison with GeForce 7600 gt, those  Radeon X1900 gt are clearly  lower then their compititor. In fact, the only   test 3D Mark 2005 where X1900 gt is higher than GeForce 7600 gt. and It is completely normal taking into account the consequent geometrical power of this Radeon .   the assessment seems more balanced with the 3D Mark 2006, the game plays show a quite different reality. Thus, Radeon X1900 gt shows on average 13% slower in the   1280 X 1024 than the GeForce 7900 gt. During the activation of filters AA (4x) and AF (8x), the performance still in favor of the GeForce 7900 gt and reached 15%. F.E.A.R. was excluded  in this resolution the “software shadows” were not activated with Radeon X1900 gt. In the best  cases, Radeon X1900 gt is negotiated with 276 € against 280 € for GeForce 7900 gt. considering that this Radeon X1900 WP IceQ3 is proposed for 330 € and GeForce 7900 gt can be equipped with a quiet cooling such as  VF-700 (25€) the overall will reach 305 €, the price ratio/performances  still  in favor of NVIDIA solution …   Overclocking and noise level Overclocking question, all GeForce 7900  GT passed between our hands had: ~20% of profit for the GPU and ~20% for the memory an increase of more than 17% in the 3D Mark 2005. Radeon X1900 gt IceQ3 from HIS did not do better. The GPU passes from 575 MHz to 607 MHz (+5.5%) while the memory goes up from 600 MHz to 729 MHz (+21.5%) with a profit of 5.5% to the 3D Mark 2005. the overclocking  plays in favor of the GeForce 7900 GT … Damage for this HIS version , its specific cooling let to us hope better than this average. With only 36 dB (A), the HIS Radeon X1900 GT IceQ3 on the other hand gains with respect to any GeForce 7900 GT which easily go more than 43 dB (A). Conclusion With its ranges of GeForce 7x00 GT, NVIDIA put ATI in not very pleasant  position  . THe Radeon X1900 GT is inclined by more than 13% compared to its direct competitor. The tariffs and especially the overclocking capability    also play big role. Overclocking borth card will give the 7900GT The total lead with over than 30% performance . 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
