first spec leak of the mobile version of the gpu

AMD Radeon R9 295X

Last but not least, the appearance of M295X should only give you a reason to expect a desktop version of Radeon R9 295X sooner or later. Rebinned Hawaii chip, 100 MHz GPU boost, slightly faster memory and we have a new competitor for 780 Ti.

AMD Radeon R9 275X

Tonga is not only a mobile chip. Actually, the first time we heard about Tonga was about desktop graphics card. It’s no secret now, that a new model will be added by AMD very soon. Since Tonga has worse specs than Tahiti (at least on paper), we assume it won’t be using R9 280 series nomenclature. Instead, it should land somewhere in-between Curacao R9 270X and Pitcairn-based R9 280. Radeon R9 275X sounds reasonable

R9 270X performance for a laptop, thats quite good. how much power will it use?

Driver: 14.300 are newer, current 14.6 are 14.200

Good to see some new cards coming through

The gtx 780m/880m are essentially desktop gtx680s with more vram as standard and slightly lower core clocks (which can then be overclocked quite easily to 1100 mhz (+) anyway. So amd have had some catching up to do for a while in the high end gaming laptop market.

The M295X looks good but 32 compute units and 2048 cores is going to need 300w+ psus and produce some impressive heat. It will probably throttle down spectacularly but lets see if they can make it work.

Looking forward to seeing the 295X. Guess its going to retake the single gpu crown. 295X to get Samsung memory? I wonder what the stock speed of it will be, hopefully its at least 1500mhz.

Why does Videocardz think that a 256bit 2048 core GCN part at 800MHz is an issue for the 880M?

~1000MHz GK104 is about on par with a 900MHz 384bit tahiti. Why would it not handily beat a 800MHz 256bit version....

Also a desktop 295X would be irrelevant as a stock clocks bump for enthusiasts. Still wouldn't even beat a Titan once OCs are taken into account. Let alone proper 780Tis.

 

[humbug]

Is the R9 275X a new Desktop GPU?

That will be interesting to compare to the R9 270X

A 275X would surely be a nice upgrade from my aging 6850.

Wonder if this chip will run cooler than the current ones, also I really hope amd have a new type of cooler for it, fed up seeing that dated, noisy, barely effective turd they seem to slap on every card for the last lot of years.
