AMD announces Radeon Instinct MI60 and MI50 accelerators using 7nm Vega and PCI-E 4.0 | VEGA 2.0?

AMD has formally announced their new Radeon Instinct MI60 and MI50 using 7nm Vega and PCI-E 4.0 .

 

AMD are claiming the MI60 is the world's fastest FP64 PCI-E capable GPU.

 

It appears these cards feature a tweaked version of the Vega architecture with Infinity Fabric and other features.

 

Oh and 1TB/s memory bandwidth is dank :D and AMD are launching their competitor to NVLink.

As part of this morning’s Next Horizon event, AMD formally announced the first two accelerator cards based on the company’s previously revealed 7nm Vega GPU. Dubbed the Radeon Instinct MI60 and Radeon Instinct MI50, the two cards are aimed squarely at the enterprise accelerator market, with AMD looking to significantly improve their performance competitiveness in everything from HPC to machine learning.

 

Quote

Both cards are based on AMD’s 7nm GPU, which although we’ve known about at a high level for some time now, we’re only finally getting some more details on. GPU is based on a refined version of AMD’s existing Vega architecture, essentially adding compute-focused features to the chip that are necessary for the accelerator market. Interestingly, in terms of functional blocks here, 7nm Vega is actually rather close to the existing 14nm “Vega 10” GPU: both feature 64 CUs and HBM2. The difference comes down to these extra accelerator features, and the die size itself.

 

Quote

With respect to accelerator features, 7nm Vega and the resulting MI60 & MI50 cards differentiates itself from the previous Vega 10-powered MI25 in a few key areas. 7nm Vega brings support for half-rate double precision – up from 1/16th rate – and AMD is supporting new low precision data types as well. These INT8 and INT4 instructions are especially useful for machine learning inferencing, where high precision isn’t necessary, with AMD able to get up to 4x the perf of an FP16/INT16 data type when using the smallest INT4 data type. However it’s not clear from AMD’s presentation how flexible these new data types are – and with what instructions they can be used – which will be important for understanding the full capabilities of the new GPU. All told, AMD is claiming a peak throughput of 7.4 TFLOPS FP64, 14.7 TFLOPS FP32, and 118 TOPS for INT4.

 

In addition to the existing FP64, FP32, and FP16 support, the new tweaked Vega cards have support for INT8 and INT4.

Omg, these accelerators and new revised Vega arch look so dank ?. I'm definitely hoping this will scare Nvidia although the chances of that happening are slim.

 

Edit: The MI60 will be launching this quarter (Q4 2018) and the MI50 will be launching in Q1 2019.

Probably not considering RX 600 series is looking like 2019 Navi series.

No, they're meant for putting in servers or racks where admins already have cooling systems in place.

No. There's been rumors they'll release a version as a Titan competitor for too much money, but this card won't generally see Consumer use.

 

It's main function was to work out all of the details for 7nm design, along with get even further into the GPU Compute space.

Considering this has the full 64 CUs enabled, why not just refresh the Vega 56 and 64 into the RX 690X and RX 690 or whatever by disabling the fancy features to turn it into a suitable replacement?

Too expensive for AMD.

 

The HBM 2.0 + memory controller cost wayyy too much (iirc memory controller costs like $100 per GPU by itself).

 

They would need to rip out the HBM2 and replace it with GDDR6 and hope the power consumption isn't worse than Vega 1.0 .

we will probably see it some pro-sumer light as a sort of frontier edition or similar. probably costing 2000+$ ish a piece. that is the only way i can see this even getting close to the consumer market.

Because it's not just a die-shrunk Vega. It's a full compute card, not a "tweener". It's also the last of the original GCN designs. Navi is some hybrid before a full redesign comes in after Navi. (Probably 2022.)

The HBM2 is probably around 600USD on its own.

For 32GB? Definitely.

 

Which would probably mean 8GB HBM2 is at least 150 USD.

 

Compared to 60 USD for 8GB GDDR5 in 2018. No idea how much more expensive GDDR6 is than GDDR5.

GamersNexus' industry contacts have 8GB of HBM2 at 150USD. That's what I used. It's the entire reason RX Vega went poorly, beyond just internal bottlenecks really keeping it down. AMD expected prices probably 1/3rd of what ended up. The DRAM price explosion hit the lower volume HBM really hard.

 

HBM is brilliant stuff, but when a good, mid-range GPU can be had for the same price as the memory, it limits it to high-end cards only. Note that Nvidia only use it on Volta. There's a reason for that.

AMD probably had plans to use it in APUs if it worked out well on the first GPUs, but prices never fell enough to make it worth it.

Just do what they did for "Rome", 2x 7nm Vega 64 GPUs with the I/O controller in the middle, 12GB of GDDR6 RAM around it, 4x 8PIN PCIe connectors and water block only cooler

As some think, I really doubt there will be 7nm RX Vega for consumers. The cost of HBM and for something that is slightly faster. So Navi should be next, mid-range and high-end I guess. Though as of now it seems that next flagship will take some time before release and by then it should have a huge generational leap in performance over Vega.

Considering that their GDDR5 controllers draw something like 45W that probably won't happen. They use HBM to keep down on power use :/

oh the controller doesn't use much power.

 

It's the actual NAND flash GDDR5 chips that does.

 

Having 8GB of NAND flash GDDR5 chips clocked that fast is power consuming. And yeah 8GB of GDDR5 uses around 50w of power on a 256 Bit bus at 7-8GHz effective.

 

Running a 512 Bit memory bus running at 5GHz effective with 4-8GB RAM would probably consume similar amounts of power if not slightly more.

as i have heard it its their IMC that is drawing all that power tho + the GDDR5. maybe im wrong but thats at least what i remember from Buildzoid talking about it.
