ATI adds another SKU to the X1900 series

There is a new Radeon X1900 series graphics card waiting in the wings. According to internal documents, ATI is set to release a single-slot Radeon X1900 GT with 36 pixel shaders. The card is in effect, a cut-down version of the Radeon X1900 XTX and is positioned to go toe-to-toe with NVIDIA's popular GeForce 7900 GT in performance and in price. CrossFire support can be enabled with an external cable connection to a Radeon X1900 512MB CrossFire Edition graphics card. 

Qualification samples of the Radeon X1900 GT are available now with production starting the week of April 14th. According to ATI, support for the X1900 GT will be added in Catalyst driver 6.4 (ver 8.241) -- which ATI expects to release tommorow or the day after. 

Here are the specs for the new card in comparison to the Radeon X1900 XTX:



Radeon X1900 GT
Radeon X1900 XTX
Pixel Shaders
36 48
Core Clock
575MHz
650MHz
Memory Size
256MB
512MB
Memory Clock
600MHz/1.2GHz
775MHz/1.55GHz

The ATI part number for the X1900GT will be 100-435803.  Samples are already apparently shipping to certain vendors and media.  The X1900GT will only require a single slot cooling solution, but it is up to the AIB partners to specify the exact cooler desired. 

Current GeForce 7900GT cards retail for just over $300.  Vendors tell us pricing has not been officially announced, but that every sign seems to indicate that the X1900 GT will show up priced at or below that $300 magic mark.  Since the Radeon X1900 GT is based on the R580 ASIC, there is already talk that an "unlock" might be in the works to convert an X1900 GT into a full blown X1900 XT.  Coupled with good heat sink solutions, and ATI's new stance on overclocking, the Radeon X1900 GT might be the next killer card this summer.

Did i miss something? nowhere did i mention the X1900 XT!? theres a 'possibility' that the card could be unlocked, which doesnt mean they will be able to. These could simply be cards that are reused when they didn't make the grade as a X1900 XT/XTX, which could mean that most of these cards wont unlock.

However the card in its current form (the GT not the XT!) will probably not defeat the 7900GT, considering that the 7900GT performs slightly better then the 7800GTX, and one 1/4 of the pixel shaders have been disabled, with slower memory/GPU clocks. Considering that theres really no ATi card out there to compete with the 7900GT at its price point , it might help push down prices for the 7900GT

The X1800XT actually beats the 7900GT in most benchmarks. ATI doesn't need a 7900GT killer. They already have one. Plus ATI x1xxx cards can do AA with HDR enabled. Can you say the same for Nvidia?

Yes, nVidia cards can't do HDR + FSAA when FP16 blends are used, but a number of games with HDR have programmed around that to allow all cards to use FSAA with HDR, ala HL2 and AoE 3. I can only imagine in a game like Serious Sam 2, Far Cry, or Oblivion, that performance would be mediocre at best. It's a nice feature but running at 1680X1050 or higher can help make up for it, and it boils down to being something not overly useful in this generation. Avivo is a better selling point for why ATi is a better buy. (Plus, I might add, ATi cards render Oblivion quite poorly according to Gamespot and some other sites, refering mainly to shadows and self shadowing).

But that's cos the self shadow feature is bugged!

Who cares if the x1900 "GT" won't beat the 7900GT? After reading more reviews, it looks like the X1800XT is very close to 7900GT and beating it in some benchmarks. Especially in AA + HDR. It is also $40 cheaper. X1900GT is placed between the X1800XT and X1900XT. So it should beat Nvidia 7900GT too.

Benchmarks don't lie and I could care either way if it's an Nvidia or ATI card in my system. But with AA + HDR, X1800XT already comes ahead of the 7900GT. Yet people somehow think it is so much faster than any ATI card.

huh? ati beats nvidia in every benchmark i've seen for oblivion. my next card is ati 4 this reason, my 6800gt aint cutting it anymore.:(
