AMD gives benchmarks free of RX 480 and RX 470 and RX reveals 480M
AMD has announced some new details about the Polaris 10 and 11 GPUs. The new slides show that Polaris 11 has 16 CUs and has a 128bit bus. An RX 480M comes with this GPU. AMD also shares some benchmark results of the RX 480 and RX 470.
The released presentation partially contains the same content as the details that AMD in the introduction announced the Radeon RX 480, but also reveals new details. It was already known that the RX 480 has 36 CUs and a 256bit bus, or the Polaris 10 GPU. The RX 470 has a Polaris 10 GPU, is clear from the presentation. Possibly it is a variant which is not fully turned on.
AMD has now announced that Polaris 11 consists of 16 CU and a 128bit bus. Probably the RX 460 gets this GPU. There will also be an RX 480M for laptops with this smaller version of the Polaris chip. Polaris 11 accounts for “more than” 2tflops. Polaris 10 was already known to be good for more than 5tflops.
Furthermore, AMD put the RX 480 in front of the R9 380 in the Steam VR Performance test. The new card scores herein according to the manufacturer 6.3, while the old model remains stabbing 3.6. The Windows 10 system where the test was carried out consisting of an Intel Core i7-5960X with 16GB RAM.
AMD also stressed that the performance per watt of Polaris is 2.8 times better than the current generation. The graphics card maker put that claim to power with 3DMark scores, which can be seen in the accompanying notes of the presentation. In the same endnotes is also an RX 480M listed under the Polaris 11 cards. This would probably be on a maximum of 35W GPU for laptops, consumption. AMD compares the GPU with the R9 M280 and while Polaris is faster, the RX 480M consumes much less.
The notes are also scores of Polaris 10 and based on benchmark results of the RX 470, said AMD. The maximum consumption would amount to 110W according to the text; Manufacturer comparing the map with R9 270x which consumes up to 180W. The benchmarks are twisted Ashes of the Singularity, Hitman and Overwatch.
