The Vega RX Thread (Rumors and Info)

[SoyCapitanSoyCapitan]

So if they can fit the full fat Vega 56 and 64 into the iMac Pro why are they shipping this fat ass double wide card with dual 8 pin connectors? To profit from all this extra component parts. I mentioned this scam in the graphics card business a few weeks ago. They simply up the voltages and add all sorts of silly bits like flashing lights and big fans to make us pay for extra junk that we don't need.

Post #43 by your own admission... That is where you got it from.
Or are you telling me, in a roundabout way, that this is your own personal blog?
If so, don't you find it a bit weird to try use yourself as your source for the veracity of this rumor?

I have already told you where it came from.

That link was to show you that not only I did got this information.

Want to see CRAZY pricing?

Look whats now on the AMD site...

Those look like older, low end, single slot cards. Some are even 512 MiB of VRAM.

I'd imagine that @Blakehoo was referring to the Radeon Pro WX 5100 and WX 7100.

Clock speeds for the Radeon RX Vega 64 are now confirmed at 1247/1546 MHz

Of course...

They're still low end, single slot Polaris or earlier cards - this is a Vega thread.

And I'm not sure that calling attention to ATI having a fire sale on cards that they're having trouble selling is really a good thing to advertise.

So... Jarred Land (president of RED Digital Cinema) posted on his FB page that AMD gave him an alpha version of a Vega-based Pro 2TB SSG GPU to test out. He compares it with the TITAN Xp. It's an insane beast. I hope Apple uses this bad boy, if they stick with AMD! Check it out:

Very interesting if it's more than a one-trick pony.

The MP6,1 is a beautiful machine for FCPX, but is often lackluster for other tasks.

It's great that a Vega SSG is good at Red raw, if that's what you're depending on to meet your payroll.

I wonder if the SSDs in the iMac Pro have some sort of direct access to the GPU. This seems like something Apple would really want to take advantage of.

Two points:

• I think that you reversed the question - it should be "do the GPUs have some sort of direct access to the SSDs".
• And... you can assume that there's no such access - if otherwise Apple would have highlighted it in the Imac Pro pre-announcement.

The ATI SSG cards have an SSD on the GPU card to give an extended tier of memory to the GPU - they don't use the SSD drives on the system.

AMD announces Radeon RX Vega 64 series

AMD Radeon RX Vega series are here. There are currently six Vega cards, two Frontiers, three RX Vega 64s and a cut-down version called RX Vega 56.

Radeon RX 56: Starting with the 56. This model has 3584 Stream Processors, 10.5 TFLOPs computing power, 410 GB/s memory bandwidth (so around 800 MHz clock) and a price tag of 399 USD.

Radeon RX 64: AMD Radeon RX Vega 64 comes in three variants. The cheapest one is 499 USD, this card has 4096 Stream Processors, 8GB HBM2 memory and 484 GB/s bandwidth. The TDP is 295W and it will offer up to 12.66 TFLOPs of power.

The fastest Vega is called RX Vega 64 Liquid Cooled Edition. This model has higher TDP (345W), but also higher clocks up to 1677 MHz. This card will cost you 699 USD.

Edit: There's also supposed to be an RX Vega 56 Nano, similar in design as the previous Radeon R9 Nano graphics card, however there are no further details available at the moment.

Apple won't even include HEVC encode/decode in their GPU drivers, let along support any other advanced features.

<facepalm>

Those are refurbished GPUs...

Another news:

Vega Nano.

Because software was not ready.

How many times it has to be repeat, that Software is defining the hardware.

In terms of low level changes this is actually pretty huge. AMD claims that IPC over Polaris has increased, but the GPU is barely faster(slower actually) per clock vs. Fiji in graphics(Geometry), and faster per clock vs Fiji, which my previous post mentioned.

It is actually bonkers. Vega on hardware level is most advanced GPU architecture we have today on planet. I have no idea why it performs in games as it currently is touted by AMD.

Just by looking at low level specs, and clock speeds it should be around... 30% faster than Titan Xp.

The GPU performs like 1.2 GHz Fiji with 512 GB/s effective bandwidth of memory.

The Vega 56 seems can fit inside the cMP very well (if that 210W TDP also reflect the real power draw).

$399 has > 10 TFLOPS, with (assuming) 8GB HBM2. It sounds like a better choice than the RX580 (if really work OOTB in MacOS, and the driver is not buggy, and the card really avail at that price in short future).

True. I have some Vega FE around in the office, but I am really looking at that one for dual card setups

The Nano is 150W TDP GPU, with only 6 pin connector. It should cost around 350-450$.

You got a source on that? I've been scouring all the tech sites for more information on the RX Vega 56 Nano, but I just find the same pictures and guesstimates based upon the R9 Nano.

Edit: It appears you may be correct on the TDP but mistaken on the connection. It appears to use an 8 pin connector.

[koyoot]

Interesting. Engineering samples have had 6 pin connector.

 

[h9826790]

I think they just want to avoid the RX480's "power gate". Even 150W TDP, still better to have 8pin, rather than accidentally kill anyone's PCIe slot.

 

[koyoot]

The GPU should be power gated, anyway, not clock gated. Power gate does not allow the GPU to draw more power than "designed". Clock gate cuts increasing of the core clock, to fit in certain power envelope, but the GPU can exceed it, anyway.

 

[tuxon86]

Or maybe, design a circuit that draw less power and perform more like their competition does, just sayin'

What a disappointing release by AMD. According to AMD, Vega 64 "trades blows" with a GTX 1080 in gaming tasks. Its 14 months later and requires more than 100 W more power. Also its almost certain Nvidia will be delivering its consumer Volta chip with GTX 1080 Ti performance at a $500 price point within the next 6 months.

I hope for AMD's sake its good enough in compute tasks that they can sell a bunch of these to data centers, because as a gaming chip its uninspiring.

If so, Your disappointment will only last for 6 months
