The video processor VP6 supports the usual formats like H.264 and can also decode and encode H.265 with a resolution of up to 4K via the NVENC API (hybrid H.265 decoder, not fully fixed function). As with previous models, 3D Vision is not supported with Optimus. HD audio formats like Dolby True HD and DTS HD can be sent to a compatible receiver as bitstream. Displays can be connected with a maximum resolution of 3840 x 2160 pixels via DisplayPort 1.2 or HDMI 2.0 (no HDCP 4K). With the GTX 965M, there can be up to 4 active displays, but this will likely decrease due to Optimus. Most of the features are identical to the GeForce GTX 800M series. Therefore, the GTX 965M SLI is powerful enough to run even the most demanding games with highest details, AA/AF and/or resolutions exceeding FullHD. In this case, the GTX 965M SLI beats a single GeForce GTX 980M by about 10 percent. With good driver support, SLI almost doubles the performance of a single card. Aside from the improved polymorphic engine in the SSMs, it is also the first Nvidia chip to support DirectX 12 Feature Level 12_1. Compared to the mid-range GM107, the newer and larger GM204 has several additional features and changes. Furthermore, the L1 (96 KB per SMM) and L2 caches (2 MB) have been significantly increased to lower the needed bandwidth. Thanks to an improved compression algorithm, the connection to the GDDR5 memory should be significantly more efficient per MHz. The memory interface has a bandwidth of 128-bits (2x 64 bit) for each of the two GPUs. In addition, there are 32 ROPs in two clusters with 16 units each. As a result, only 1024 shader ALUs and 64 TMUs are active. But, in the GeForce GTX 965M, Nvidia have deactivated 8 of 16 SMMs. The GM204 features four GPCs, and each consists of four SMMs. Now each SMM contains only 128 shader units and 8 TMUs, which is noticeably less than an equivalent Kepler GPU. Among other changes, Nvidia have restructured the streaming multi processors (SMM) in order to increase workload and efficiency. GM204 is based on Nvidia's Maxwell architecture, which replaces the previous Kepler generation. This happens because of different timespans between two frames (e.g., irregular delays between sequential frames). Therefore, it may suffer from micro stuttering in low fps ranges of 30 fps. With SLI, each card renders a single frame (AFR mode). The clocks for the SLI-setup are usually identical to a single GTX 965M (924 MHz GPU, 1250 MHz memory). Each card has a 28 nm GM204 GPU based on the Maxwell architecture, which is the same chip as found on the GTX 980M, GTX 970M as well as several desktop cards. The NVIDIA GeForce GTX 965M SLI is a high-end DirectX 11-compatible graphics solution for laptops, consisting of two GeForce GTX 965M. NVIDIA GeForce GTX 965M SLI ► remove from comparison used by AMD and also for the professional GA100 Ampere chip). The GA103S chip is manufactured by Samsung in 8nm (8N), which is not quite able to keep up with the 7nm node at TSMC (e.g. 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 raytracing and tensor cores on the chip were also improved according to Nvidia. With Ampere, all shaders could still execute FP32 or INT32 instructions. The GA103S chip offers 7424 FP32 ALUs of which half can also execute INT32 instructions (i.e. The desktop variant of the A5500 however, is a lot faster. At a similar power consumption level, the RTX A5500 should be clearly faster than the old RTX A5000 и Quadro RTX 5000. Both GPUs depend heavily on good cooling and a high TGP for good performance. The raw performance should be similar to the GeForce RTX 3080 Ti laptop at the same TGP level. There is no more Max-Q variant (formerly used for the low power variants) but every OEM can choose to implement Max-Q technologies (Dynamic Boost, Whispermode). The GPU supports eDP 1.4b to connect the internal monitor and DisplayPort 1.4 and HDMI 2.1 for external connections. It supports PCIe 4.0 and will be available in different variants from 80 - 165 Watt (TGP) with different clock speeds (and performance). It offers the same 7424 graphics cores, 58 RT cores, 232 Tensor cores, and 16 GB GDDR6 graphics memory with a 256 Bit memory bus. It is based on the GA103S Ampere chip and similar to the consumer GeForce RTX 3080 Ti Laptop GPU. The NVIDIA RTX A5500 Laptop GPU or A5500 Mobile is a professional graphics card for mobile workstations.
