Key specifications of Radeon’s upcoming Vega GPUs have been revealed alongside Apple’s announcement for the iMac Pro, ironically. For those who many not know, Apple’s upcoming powerhouse, the iMac Pro, will come fitted with a Vega-based graphics card.
That aside, let’s talk about Vega. According to Apple’s iMac Pro specifications, consumers will be able to opt for either a Radeon Pro Vega 56 graphics card or a more powerful Radeon Pro Vega 64 GPU. The former graphics card apparently comes with 8GB of HBM2 memory, while the latter comes with 16GB HBM2 memory.
There’s also something rather interesting about the naming convention of Radeon’s upcoming Pro Vega graphics cards. It seems that their names also indicate the amount of CUs (compute units) that they may feature. For instance, the Radeon Pro Vega 56 may likely come with 56 CUs, while the Radeon Pro Vega 64 may feature 64 CUs.
If this were indeed the case, then it looks like Radeon’s Vega-based graphics cards may have some similarities with the company’s older Fiji GPUs. Radeon’s Fury X, for example, came with 64 CUs, while the Radeon Fury came with 56 CUs – coincidence?
Also worth mentioning is the fact that the Vega-based graphics cards that’ll come with the iMac Pro will come with lower FP32 compute performance compared to Nvidia’s Titan Xp. That said, we still don’t know whether these are the most powerful Vega graphics card, yet. That information, along with other enticing Vega announcements may only be revealed in late July, during Siggraph 2017.
