Depending on the manufacturer, first-generation GDDR6 is generally promoted as offering up to 16Gbps per pin of memory bandwidth, which is 2x that of NVIDIA’s late-generation GDDR5 cards, and 40% faster than NVIDIA’s most recent GDDR5X cards.Relative to GDDR5X, GDDR6 is not quite as big of a step up as some past memory generations, as many of GDDR6’s innovations were already baked into GDDR5X. The advantage here – at least as much as we saw in Volta – is that it speeds up address generation and Fused Multiply Add (FMA) performance, though as with a lot of aspects of Turing, there’s likely more to it (and what it can be used for) than we’re seeing today.The Turing SM also includes what NVIDIA is calling a “unified cache architecture.” As I’m still awaiting official SM diagrams from NVIDIA, it’s not clear if this is the same kind of unification we saw with Volta – where the L1 cache was merged with shared memory – or if NVIDIA has gone one step further.

Which is why NVIDIA, the video card company, is going to be pushing the visual aspects of all of this harder than ever.Overall then, hybrid rendering is the lynchpin feature of the GeForce RTX 20 series.
But at a very high level it sounds like the next generation of NVIDIA's multi-res shading technology, which allows developers to render different areas of a screen at various effective resolutions, in order to concentrate quality (and rendering time) in to the areas where it's the most beneficial.As the memory used by GPUs is developed by outside companies, there are no big secrets here.
Here are the
We know that NVIDIA is exclusively using Samsung's GDDR6 for their Quadro RTX cards – presumably because they need the density – however for the GeForce RTX cards the field should be open to all of the memory manufacturers.
Going by their Gamescom and SIGGRAPH presentations, it’s clear that NVIDIA has invested heavily into the field, and that they have bet the success of the GeForce brand over the coming years on this technology.
It looks like the RTX 2070 is taking the place of the GTX 1080 in terms of heat and power while the RTX 2080 and the Ti variant are reaching much higher. 50GB/sec is a big improvement over HB-SLI, however it’s still only a fraction of the 448GB/sec (or more) of local memory bandwidth available to a GPU.
In particular here, it’s inheriting one of Volta’s more novel changes, which saw the Integer cores separated out into their own blocks, as opposed to being a facet of the Floating Point CUDA cores.
All three features are inherently based on the properties of light, which in simplistic terms moves as a ray, and which up to now various algorithms have been faking the work involved or “pre-baking” scenes in advance.
The RTX 2080 Ti will start at $999 for partner cards, while the RTX 2080 will start at $699.
The GeForce GTX cards will be implementing SLI over NVLInk, with 2 NVLink channels running between each card.
us), however I have to admit that I don’t imagine there’s going to be much stock available by the time reviews hit the streets.So what does Turing bring to the table?
