[WCCFTech] AMD Radeon Instinct MI100 With Arcturus GPU Spotted – 32 GB HBM2 Memory, 200W TDP In Early Prototype

AMD's upcoming Radeon Instinct MI100 HPC accelerator which would feature the Arcturus GPU has been spotted by Komachi. The existence of the AMD Arcturus GPU was confirmed all the way back in 2018 and two years later, we are finally starting to get details regarding the specifications for AMD's next HPC/AI accelerator.

The Radeon Instinct MI100 test board has a TDP of 200W and is based on the XL variant of AMD's Arcturus GPU. The card also features 32 GB of HBM2 memory with pin speeds of 1.0 - 1.2 GHz. The MI60 in comparison has 64 CUs with a TDP of 300W while clock speeds are reported at 1200 MHz (Base Clock) while the memory operates at 1.0 GHz along with a 4096-bit bus interface, pumping out 1 TB/s bandwidth. There's a big chance that the final design of the Arcturus GPU could be featuring Samsung's latest HBM2E 'Flashbolt' memory which offers 3.2 Gbps speeds for up to 1.5 Tb/s of bandwidth.

It is also mentioned that the Arcturus XL GPU could be a single huge monolithic die and not a chiplet based design like AMD's Zen 2 based Ryzen CPU lineup. The naming of the Radeon Instinct MI100 itself gives us a hint of its absolute performance metrics which would be around 100 TFLOPs of INT8. That's a 66% increase in INT8 (AI/DNN) compute horsepower. Similarly, the FP16 compute would be rated at around 50 TFLOPs, 25 TFLOPs of FP32 and 12.5 TFLOPs of FP64. The extra GPU horsepower could be coming through either an updated graphics architecture, much higher clocks or higher CUs, which is the best assumption.
I don't usually post rumors but I've been excited about Arcturus ever since I got my hands on my Radeon VII. I'm really hoping they release another prosumer card like the Radeon VII based on Arcturus even if it was $1200-$1500. The rumored specifications are absurd.

AMD has been working for a while to improve their perf/watt in their gpus. To the point of the current mess with clock flickering. 2.5x perf/watt sounds implausible. 32GB HBM sounds doable. MI100 on GCN would mean close to 3ghz clocks or doubling operations at lower clocks. Neither would be an improvement for 7nm power consumption. 400w sounds more plausible.

Making the biggest chip run 200w doesn't sound like they are still competing. That would be like Nvidia selling a midrange sized die for flagship prices, but with no flagship on the horizon.

Radeon 7 was a mistake. No way AMD is releasing MI cards as gaming cards. RDNA will do WS and Gaming while GCN will do MI.

The Radeon VII wasn't a mistake, it was a bargain. Who mentioned gaming?

though tbh i'm fairly certain even if you gave those guys a tesla or instinct they'd still think they're gaming cards.
edit: it would be hilarious if those guys says that the cards are useless because it doesn't support display port.

trolling an adult is very dangerous, don't try it at home nor at work. you don't want to play tag with a rabid man.

Indeed! Anyone remember the entitled whining in the Titan RTX thread?

people include gaming in "prosumer" cuz it'll run games.

it's a win for AMD, if they can emulate Titan's success. Gotta remember, they didn't start @ $2500. They started @ $999. NVidia has built a ton of cushion thanks to AMD's flailing. This now benefits AMD too, if they can release a competent product & trigger full blown duopoly scams. if so, then our only hope is Obi and Intel. N my money is on Obi.

R.I.P. Zawarudo, may you OC angels' wings in heaven.
If something appears too good to be true, it probably is.
Best R0ach Quote of all time : TLDR: Haswell might be the last legit gaming platform unless mice get their own non-USB interface on some newer architecture.

Obi?

Is there some new thing I can spend money on?

AMD Titan was Vega FE. If they are going to release Titan GPU it will be based on RDNA. I dont expect to see the prosumer of MI card from AMD. They have to fill out all these servers with these GPUs and Epyc CPUs.
