In exactly one week from now, AMD will unveil its Radeon RX 6000 series lineup, whatever that might ultimately consist of, finally putting to rest the bulk of related rumors and leaks. All we can say for 100 percent certainty right now is that the new cards will be based on AMD's RDNA 2 graphics architecture. That said, a roundup of leaks suggest the highest-end variants will be monster GPUs. Let's hope that is true, because we sorely need some competition in the high-end GPU space. For the past several years, NVIDIA has dominated the sector, with Pascal, Turing, and now Ampere. NVIDIA's latest generation GeForce RTX 30 series is a formidable lineup, setting a high bar for AMD to meet, exceed,... Read more...
The AV1 video codec created by the Alliance for Open Media promises big gains in video quality for a given bitrate. The new codec also delivers an open, royalty-free standard that the consortium hopes to use to replace Motion Picture Entertainment Group's (MPEG) H.264 and Google's VP9. AOM says that AV1 can achieve 50% better compression with the same image quality compared to H.264, so it's bound to save some bandwidth. Video encoded with AV1 has been out there for a while, but has required CPU intervention to decode. Now AV1 can be accelerated by graphics hardware, but the requirements are kind of steep.  First of all, you'll need a brand new graphics processor, or perhaps one that hasn't... Read more...
For the past several weeks, it has been rumored that Big Navi will burst onto the GPU scene wielding 80 compute units (CUs), making it a potential monster. To put that into perspective, it is twice the number of CUs as the current generation Radeon RX 5700 XT. Now we have the closest thing yet to a confirmation, by way of reverse engineering a macOS driver. It seems AMD is getting its ducks in a row, and in the process, inadvertently (or perhaps on purpose) left a trail of finely ground bread crumbs, for those willing to look. Reddit user stblr did exactly that, and posted directions on how to view the data for yourself. It consists of the following steps... Install macOS 11 beta (obviously you... Read more...
One thing we know for sure is that Big Navi is coming. AMD has not kept this a secret, even going so far as to say it will be a halo product. How it will fare against Ampere remains to be seen, but make no mistake, AMD has every intention of competing at the high end of the graphics market. The question is, will Big Navi arrive with HBM2e or GDDR6 memory? Almost definitely the latter, though the rumor mill is undecided on the matter. AMD has not shied away from HBM memory in the past, which offers gobs of bandwidth. However, it is generally more expensive than GDDR memory. Combined with potential supply issues, it makes sense to choose GDDR6 for AMD's next-gen GPUs, as NVIDIA will presumably... Read more...
This is shaping up to be a big year in GPUs. Intel is gearing up to launch its first discrete GPU of the modern era, NVIDIA recently announced its next-generation Ampere GPU (which will find its way into gaming graphics cards), and AMD is prepping a round of Navi GPUs based on its RDNA 2 architecture. As it pertains to the latter, a fresh leak purportedly offers up some interesting details. To recap, RDNA 2 is being injected into Microsoft's Xbox Series X and Sony's PlayStation 5 consoles, which are slated to arrive later this year. In addition, RDNA 2 will land on PC as well. Rumor has it RDNA 2 will offer a major performance uplift over RDNA 1, and it's been confirmed at least some of the GPUs... Read more...
AMD introduced its first Navi 10-based GPUs over the summer starting with the Radeon RX 5700 and Radeon RX 5700 XT. While these are excellent mainstream GPUs based on 7nm process tech, they by no means offer flagship-caliber performance. However, if these latest rumors are accurate, AMD will have a true Radeon VII successor on its hands with the alleged Navi 21 GPU. Navi 21 will be based one second-generation RDNA architecture, and will take advantage of refined 7nm+ process tech.  Based on comments posted to the Taiwanese forum PTT, Navi 21 will roughly be twice the size of Navi 10, coming at a 505mm2 versus 251mm2. To put in perspective how big this GPU is, the Radeon VII (Vega 20)... Read more...
