AMD Tahiti (Radeon HD 7900) Graphics Card Seen in the Nude

Today may be a Fringe-less Friday but worry not, there are plenty of thing to do like contemplating the two recently-leaked images of an AMD Tahiti-powered graphics card. Tahiti is a 'next-gen' GPU built on TSMC's 28 nm process that's supposed to be at the heart of the Radeon HD 7900 series models (the HD 7950, HD 7970, and then probably the dual-GPU HD 7990).

AMD Radeon HD 7900 ''Tahiti'' Pictured, 384-bit Memory Bus Confirmed?

A Beyond3D forum member posted a mysterious picture of two graphics cards that could very well be engineering samples of AMD's true next-generation Radeon HD 7900 "Tahiti" graphics cards. The final products most probably won't look like these, with a bare red PCB, but it does look like the reference cooler design is ready. A more important feature in that picture is the spotting of traces for at least 11 memory chips, the 12th one (not highlighted) is apparently near the PCIe slot interface. The presence of 12 memory chips gives rumors of Tahiti featuring a 384-bit wide memory interface a shot in the arm. This will be the first AMD GPU in over 5 years to feature a memory bus wider than 256-bit. The R600 Radeon HD 2900 GPU featured a 512-bit GDDR4-capable memory interface.

AMD Radeon HD 7400M, HD 7500M, and HD 7600M Released

Over the week, AMD launched three of the first notebook GPUs in the Radeon HD 7000 series in a bid to stay competitive in the notebook GPU market, even if it means re-branding already launched GPUs like NVIDIA did, with its recent GeForce 600M series launch. The newly [re]launched mGPUs include Radeon HD 7400M, HD 7500M, and HD 7600M. The three are based on current-generation Caicos and Turks GPUs.

Compare AMD A6-3400M Vs Intel Core i3-2310M

It is easy to be mislead by clock speed to conclude the a lower clock speed means slower processor. AMD’s newest fusion processor – the A6-3400M is clocked just at 1.4 GHz and you may be tempted to conclude that it is slower than the Intel’s core i3-2310M, clocked at 2.1 GHz.
