More dies mean better yields and more graphics cards to go around. At an estimate, Nvidia can get around 130 dies per wafer with GA104 (some of which are defective, most of which end up as partially disabled chips), while the smaller size of GA106 allows for around 200 dies per wafer. That shrinks the die size from 393mm square to just 276mm square, which not only helps to reduce the cost of the chip, but also increases the number of chips Nvidia can get from a single wafer - and if you're wondering, GA106 is less than half the size of GA102, which measures 628.4mm square and has 28.3 billion transistors. The full GA106 chip has 12 billion transistors, down from 17.4 billion in GA104. Finally, there are six 32-bit memory interfaces, each one linked to a single 8Gb or 16Gb GDDR6 module - the latter is reserved for desktops at present, with the 8Gb modules used on laptops. ![]() The SMs also contain one second-gen RT core and four third-gen Tensor cores, each of which is up to twice the performance as the previous generation cores, and with sparsity the Tensor cores are potentially four times as fast as on Turing. The good news here is that entry level GPUs such as the RX 580, 5500 XT and GTX 1650 Super are still able to deliver playable performance, with around 30 fps on average. (Note that the mobile RTX 3060 has all 30 SMs enabled, though it only comes with 6GB of memory, which is also clocked lower than on the desktop card.)Įach SM contains 64 dedicated FP32 CUDA cores, plus 64 more FP32+INT32 CUDA cores - only FP32 or INT32 can be used for each cycle. It features 2048 shader units, a boost frequency of 2539 MHz, 8 GB of GDDR6 memory and a 160W TDP. The RX 6600-XT is AMDs best value for money 6000 series GPU. It supports all the APIs including OpenGL, OpenGL ES, Vulkan, Metal, DirectX/Direct3D, and DirectX 12. Device: 1002 73FF Model: AMD Radeon RX 6600 XT. It measures GPU performance with next-gen graphics features on all platforms. The full chip has 30 SMs while the 3060 disables two and ends up with 28 SMs, but everything else is left alone. Another free and extremely efficient GPU comparison tool to consider is GFXBench. At a high level, there are three GPCs (Graphics Processing Clusters), each with up to 10 SMs and 16 ROPs (the two blocks of eight blue rectangles each at the bottom of the GPC). This is the first desktop card to use Nvidia's GA106 processor. ![]() Power use remains similar, with a 170W TGP (Total Graphics Power), a decent step down from the RTX 3060 Ti's 220W TGP. It also doubles VRAM capacity (at least until the anticipated RTX 3060 6GB shows up, though perhaps maybe Nvidia will just leave that for the RTX 3050 line) and boasts improvements in the RT and Tensor cores, as well as the memory subsystem, all leading to better performance. Ampere gives you a lot more shader cores, which means potentially much higher computational performance, and a minor improvement in memory bandwidth for the 12GB card. GravityMark GPU Benchmark demonstrates the capabilities of modern GPUs by rendering an enormous quantity of objects in real-time, utilizing GPU acceleration. The RTX 20 Super show how much things have changed for the -60 suffix cards between Turing and Ampere. Here's how things break down, comparing the RTX 3060 with its closest Ampere sibling and Turing predecessors.
