nuove schede ati

The Inquirer

ATI IS READYING a further onslaught in its increasinly vicious battle with Nvidia for market share.

And so it's readying some further introductions later this year. The first chip, the RV560, features eight ROP units and is capable of pushing out eight pixels per clock, which is double the number of the current X1600 (RV530).

The number of Pixel Shader ALUs (arithmetical logical units) will also get a boost, and the RV560 will feature 24 of them, with four Vertex Shader units. The number of Texture Memory Units (TMU's) has also been raised from four to eight, since there is no logical reason to have fewer textures than pixels per clock.

The second chip, the RV570 will truly be a mainstream monster, which should give Nvidia a headache. The chip is scheduled to have 12 ROP and 12 units (12 pixel/textures per clock), 36 Pixel Shader ALU's and six Vertex Shaders. Clock speeds are not defined, but you can expect 650 or even a 700MHz GPU clock for the X1700XT part. It all depends on yields.

ATI's 80 nanometre mainstream parts are almost certain to be named X1700, although we have no confirmation about the suffixes used for two different chips. We know that two RV570 based models are likely to be named X1700XL and X1700XT, while the RV560 will find itself in the X1700Pro range. Unless the company pulls out an X1500 moniker to differentiate the two - and it would be interesting to see X1500 outperforming X1600 by a mile. At the same time, X1300 will occupy the low-end, and the X1600 should slowly fade away to leave room for different clocked RV560/570 parts.

But first, the time approaches for the launch of X1900XL, a successor to X1800XL, also known as "the quiet X1800 board". As you may guess, nothing has changed from its faster brother - we're talking about 16 ROP units, 48 Pixel Shader and eight Vertex Shader ALU chips with the GPU clock speed ranging between 500 and 560MHz. Memory used in this value-friendly product will be Samsung or Infineon 1.4ns GDDR-3 modules, which will result in memory clocks ranging from 600 to 695MHz so expect either 1200 or 1360/1390MHz.

The price of the board is similar to the 7900GT, hovering around $299. The board however, will be pretty expensive to make, so don't expect to see many happy faces on the booths of ATI partners during the Taiwanese Computex show. This "high-end mainstream" should buy enough time for ATi to prepare its 80nm die-shrink, which we hear is more than a die shrink. ATI is obviously mulling Nvidia's G70>G71 style. µ

fosse così ritornerebbe a fare una buona fascia media

il fatto è che io di inquirer mi fido poco anzi pochissimo..se è vero sarebbe una buona cosa anche sè la fascia media di ati oggi è la 1800..che si comporta benissimo direi...

Spero di cadere nel crossposting, ma ho trovato solo ora questa discussione...
Il fatto è che sto chiedendo info ovunque sulle X1900XL, dato che non ne avevo più sentito parlare... Quando pensate che usciranno? Ma soprattutto, c'è chi si lamenta delle differenze prestazionali tra una X1800XT con Bios OC e una X1900XT, troppo lievi per giustificare il divario nei prezzi.... Ma allora come si posiziona questa X1900XL? Sarà più performante di una X1800XT 512MB?

16 ROP units, 48 Pixel Shader and eight Vertex Shader ALU chips with the GPU clock speed ranging between 500 and 560MHz. Memory used in this value-friendly product will be Samsung or Infineon 1.4ns GDDR-3 modules, which will result in memory clocks ranging from 600 to 695MHz so expect either 1200 or 1360/1390MHz.

Ma una X1800XT 512MB non aveva 625MHZ per la GPU e 1500 per le memorie? Il passaggio da 16 a 48 pixel shader compensa?

Come vedete sono moolto confuso...
