First things first, the new CPU family will carry the “RYZEN” brand pronounced, risen. Thanks to a leak by VCZ we have learned several new exciting things about AMD’s next generation family of desktop Zen processors, code named “Summit Ridge”. It sounds like the stuff of sci-fi and fan fiction, but it’s very much real. Which automatically boosts the clock speed of RYZEN CPUs beyond their official nominal values and stretch them as far as the cooling will allow, without any intervention from the user. It’s all thanks to a new technology that the company calls “XFR”, short for Extended Frequency Range. AMD’s upcoming enthusiast line of “Summit Ridge” desktop processors based on the Zen microarchitecture come with an auto overclocking feature right out of the box. They boast 8 cores, 3.4Ghz+ clock speeds & will overclock themselves automatically. So basically a game that says it uses 4GB of VRAM right now, is in actuality using 2 and with Vega, you’re saying, it will actually allocate 2.ĪMD’s new desktop Zen CPUs are officially called RYZEN. So effectively you can think of it as Vega will be doubling your memory capacity for games. So with Vega and with the High Bandwidth Cache and the HBC controller, for games it will utilize the amount of frame-buffer you have much more efficiently. That’s because the current/old GPU architecture doesn’t give you flexibility to move memory in fine granularity. So if the game say needs 4GB of memory when we looked at actually how much of that memory is actually used to render pixels we found that many games, actually most games, don’t use more than 50% of what they allocate. We look at how much of the VRAM that the game allocates. We looked at all the modern games, the big games that push memory hard, and one of the things we noticed is the VRAM – graphics memory – utilization. With regards to the High Bandwidth Cache from a gaming perspective. Raja Koduri – Chief Architect Radeon Technologies Group, AMD And who is better to explain it all than AMD’s top graphics man and beloved nerd Raja Koduri. It’s all thanks to the company’s brand new High Bandwidth Cache Controller at the heart of every Vega graphics chip and the way it works is quite clever. We’re not going to dive into the details here, so if you want to read more about it we’d highly recommend checking out that article.Īn 8GB Vega graphics card, just as an example, will be effectively have as much usable memory as a 16GB graphics card. We go into a lot of details on how it works and why it’s quite revolutionary in our Vega graphics architecture piece, where we break it all down. One of its features in particular is impressive enough to warrant having its own discussion.īesides handling memory traffic in a vastly more efficient fashion it also significantly cuts back on wasteful memory allocations. The new memory architecture allows Vega GPUs to do a number of exciting new things that its predecessors can’t. Perhaps the most intriguing and exciting of all the new bells and whistles that Vega brings to the table is its unique memory architecture and High Bandwidth Cache. AMD’s Vega Will Double Your Usable Graphics Memory Capacity With Its Clever New High Bandwidth Cache
