AMD Radeon HD 7290 vs AMD Radeon HD 7340
AMD Radeon HD 7290► remove
The AMD Radeon HD 7290 (or sometimes also called ATI Mobility Radeon HD 7290) is an integrated graphics card in some Ontario netbook processors (e.g., C-70). Technically the 7290 is just a renamed Radeon HD 6290 and therefore also based on the same graphics core as the ATI Mobility Radeon HD 4330 but without any dedicated memory. Furthermore, it features the newer UVD3 video processor. Compared to the slower HD 6250, the 7290 / 6290 features Turbo Core to overclock automatically to 400MHz.
The 3D performance of the HD 7290 is located in the low end above the integrated chipset graphics card of the 880M chipset (e.g. Radeon HD 4250). Due to the slow processor, the gaming is however very restricted. Only very old and low demanding games run fluent in low-medium detail settings (e.g. Half Life 2). Even non demanding games like Trackmania Nations Forever can only be played in low details. However, compared to the integrated graphics card in Atom processors (GMA 3150), the HD 7290 clearly wins.
The new UVD3 video decoder allows the decoding of HD videos using the graphics card. It allows the parallel decoding of two MPEG2, H.264 and VC-1 streams and therefore compatible to BD-Live. Furthermore, the new UVD3 also supports DivX, Xvid and MPEG4 Part 2 decoding. Blu-Ray 3D via MCV (Multiview Video Coding) of the UVD3 is not supported due to the low processing power.
The power consumption of the HD 7290 is quite low as it is directly integrated in the processor. The whole processor containing northbridge parts, a memory controller and the GPU is specified with 9 Watt TDP.
AMD Radeon HD 7340► remove
The AMD Radeon HD 7340 (or perhaps also called ATI Mobility Radeon HD 7340) is an integrated graphics card in the 2nd generation Zacate netbook processor. It is based on the same graphics core as the Radeon HD 6320, but the base clock and the turbo boost is somewhat higher. Furthermore, it features the UVD3 video processor.
The 3D performance of the HD 7340 is about 10 percent faster than the HD 6320. Gaming performance are therefore similar to a Nvidia ION or Intel HD Graphics graphics card. In our tests the HD 6320 was only able to run low end games like Fifa 11, Sims 3 and Star Craft 2 single player in lowest detail settings fluently. More demanding games like Risen or Call of Duty series were not playable.
The UVD3 video decoder allows the decoding of HD videos using the graphics card. It allows the parallel decoding of two MPEG2, H.264 and VC-1 streams and therefore compatible to BD-Live. Furthermore, the new UVD3 also supports DivX, Xvid and MPEG4 Part 2 decoding. Blu-Ray 3D via MCV (Multiview Video Coding) is theoretically supported by the UVD3 but wasn't available in the first laptops and platforms (no hardware accelleration and no HDMI 1.4 output).
