Ah, those crafty European online retailers, always listing new graphics cards and processors before they actually launch. This time, two unannounced AMD graphics cards—the Radeon HD 5750 and Radeon HD 5770—have made their way onto the Geizhals.eu price search engine.
Both listings point to the same two e-tailers, which charge the following for the upcoming cards: €119.90 for the 5750 and €149.90 for the 5770. To give you an idea of how those prices might translate across the Atlantic, the cheapest Radeon HD 5850 listings are around €230 at those e-tailers and $260 at Newegg. So, don't go making a straight currency conversion and thinking the 5770 will set you back over $200 in the States.
Neither listing details specs beyond the memory capacity, which is 1GB for the Radeon HD 5750 and 5770. However, Geizhals talks of Juniper graphics chips, stream processor counts over 1,000, and GDDR5 memory piped through 128-bit interfaces in both cases. Actually, the only difference it quotes is a higher clock speed for the 5770. That sounds a tad hard to believe considering how AMD has segmented its mainstream graphics cards in the past, though. (Thanks to Fudzilla for the heads up.)
