New AMD Graphic Cards in October 2018?
AMD Polaris 30 (12nm LPP)? RX 650, 660, 670 & 680?
Lately circulates a rumor about the possible new AMD Graphics cards, using the Polaris 30 architecture, being it a node shrinkage with the capability of higher clock speeds and lower power consumption.
Supposedly this will be called RX 600 series (supposedly). What do you think about it? A good investment for AMD’s low and mid-end markets? We sure do hope so!
Newer cards will probably be called RX 600 series since AMD said they would go back to the previous naming scheme before the VEGA cards.
Ex-AMD Radeon chief, Raja Koduri, fueled rumours of a potential MCM GPU design for Navi when he claimed Infinity Fabric was core to all of the red team’s future designs.
“Infinity Fabric allows us to join different engines together on a die much easier than before,” Koduri says. “As well it enables some really low latency and high-bandwidth interconnects. This is important to tie together our different IPs together efficiently and quickly. If forms the basis of all of our future ASIC designs.
“We haven’t mentioned any multi-GPU designs on a single ASIC, like Epyc, but the capability is possible with Infinity Fabric.”
“Anything’s possible… But you know if you think about this big GPU it’s actually multiple pipelines, multiple rendering interfaces, so in theory, you can slice it in half. But the devil’s in the details because when you slice in half and you’ve got to make the interface invisible to a programmer, that means your interface has to be very wide and very, very high-speed so that it can look and feel like one chip.
That’s the complexity. Because it’s hard to be done that way, that’s why people do CrossFire because that communication’s centered around a narrow, fast interface.
“Do you make that interface indefinitely wide and fast so it feels like a single die? But then it will become a physical implementation issue, whether that can be done.”
The company had already demonstrated working 7nm GPU silicon back in June at Computex, which has been sampling since and is set to be available for purchase later this year.
Based on an improved iteration of the Vega architecture which debuted last year, 7nm Vega is nothing short of a beast. The new GPU supports intrinsic AI instructions and features four HBM2 8GB stacks running across a 4096-bit memory interface for a total of 32GB vRAM.

Whilst the company hasn’t disclosed detailed specifications relating to the new GPU we could reasonably expect around one terabyte/s of memory bandwidth, higher clock speeds, and significantly better power efficiency thanks to TSMC’s leading-edge 7nm process technology, which has reportedly enabled the company to extract an unbelievable 20.9 TFLOPS of graphics compute out of 7nm Vega, according to one source.
If true, it would make it the world’s first 20 TFLOPS GPU.
