AMD Radeon HD 6950M vs NVIDIA GeForce RTX 3050 vs AMD Radeon HD 6990M

AMD Radeon HD 6950M

The AMD Mobility Radeon HD 6950M (or sometimes called ATI Mobility Radeon HD 6950) is a high-end graphics card generally used for big and heavy laptops. It is based on the desktop HD 6850 graphics card and therefore features the new UVD3 video processor, increased Tessellation performance and Eyefinity+. The codename of this GPU is Blackcomb Pro and it should have similar power consumption as the GeForce GTX 470M. Compared to the faster HD 6970M, the 6950M's core is clocked slower by at least 100 MHz.

The 960 Stream processors should be still based on the "old" 5D architecture, similar to the 5000 series. Therefore, the number of shaders in the 6950M is not comparable to the 1D cores of current Nvidia GPUs. The Tessellation performance, however, should be improved (like the desktop 6800 series) with the new cards. The Stream processors can be used with DirectX 11, OpenGL 4.1, DirectCompute 11 and OpenCL. With the latter two, the cores of the 6950M can also be used for general computations like video transcoding.

The 3D performance is on par with the GeForce GTX 470M in the high end class of notebook graphic cards. For gamers, this means that the Radeon HD 6950M is able to fluently play most modern games (as of 2011) in high detail settings. Only Crysis and Metro 2033 will stutter in the highest detail settings at 1920x1080 resolution (see below).

The new UVD3 video decoder supports the decoding of MPEG-4 AVC/H.264, VC-1, MPEG-2, Flash and now also Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos on the graphics card.

Furthermore, the HD 6900M series integrates an HD audio controller to transmit HD Audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g., for Blu-Ray videos).

The AMD HD3D Technology offers support for Blu-Ray 3D and 3D displays (integrated and external). However, the solution is not as mature as Nvidia's 3D Vision.

Thanks to Eyefinity, the graphics chip is able to theoretically drive up to 6 monitors simultaneously provided that the notebook itself has enough video-out ports.

The power consumption of the 6950M should be similar to the Nvidia GeForce GTX470M and is therefore only suited for medium to large laptops with good cooling solutions.

NVIDIA GeForce RTX 3050

The Nvidia GeForce RTX 3050 is a mid-range desktop graphics card. It is based on the GA106 Ampere chip and offers 8 GB GDDR6 graphics memory with a 128 Bit memory bus. It offers 2,560 cores and supports PCIe 4.0.

The performance is similar to the older GeForce RTX 2060 and therefore best suited for 1080p gaming of modern and demanding games in high settings.

The GA106 chip offers 3,840 FP32 ALUs of which half can also execute INT32 instructions (i.e. 1,920 INT32 ALUs). With Turing all shaders could still execute FP32 or INT32 instructions. The raytracing and tensor cores on the chip were also improved according to Nvidia. The Ampere chips also include an improved 5th generation video encoder (NVENC for H.264 and H.265) and a 7th generation decoder (for various formats now including AV1).

The GA106 chip is manufactured by Samsung in 8nm (8N), which is not quite able to keep up with the 7nm node at TSMC (e.g. used by AMD and also for the professional GA100 Ampere chip). The TDP of the RTX 3050 is specified at 130 Watt and therefore better than the previous RTX 2060 (160 Watt).

AMD Radeon HD 6990M

The AMD Mobility Radeon HD 6990M (or sometimes called ATI Mobility Radeon HD 6990) is a high-end graphics card for large laptops (17" and up). It is based on the desktop HD 6870 graphics card and there supports UVD3 decoding and Eyefinity+, albeit with overall reduced clock rates.

The 1120 Stream processors are still based on the "old" 5D architecture similar to the 5000 series. Therefore, the number of shaders is not comparable to the 1D cores of current Nvidia GPUs. The Tessellation performance should be improved (like the desktop 6800 series) with the new cards. The Stream processors can be used with DirectX 11, OpenGL 4.1, DirectCompute 11 and OpenCL. In particular, DirectCompute 11 and OpenCL can both allow the cores to be used for general computations like video transcoding.

The 3D performance should be similar to the Nvidia GeForce GTX 580M in the high end class of notebook graphics cards. Therefore, as of 2011, most modern and demanding games should run in full HD with highest settings fluently. Only Metro 2033 and Crysis (DX11) may need reduced detail settings.

The new UVD3 video decoder supports the decoding of MPEG-4 AVC/H.264, VC-1, MPEG-2, Flash and now also Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos on the graphics card.

Furthermore, the HD 6900M series integrates an HD audio controller to transmit HD Audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g. für Blu-Ray videos).

The AMD HD3D Technology offers support for Blu-Ray 3D and 3D displays (integrated and external). However, the solution is not as mature as Nvidia's 3D Vision.

Thanks to Eyefinity, the graphics chip is able to theoretically drive up to 6 monitors simultaneously. However, this only works if the laptop features enough DisplayPort outputs.

The high power consumption of the chip limits its use only in large laptops with good cooling solutions (e.g. Alienware M18x or Clevo X7200).
