AMD launched a whole refresh cycle of its midrange graphics playing cards immediately. Whereas our review focuses on the RX 580, AMD can be delivery new SKUs for the RX 460 and 470, in addition to a brand new half, the RX 550. Let’s step by means of what’s modified for these chips, and what the updates imply for avid gamers in these market segments.
RX 560 and RX 570
The RX 560 and RX 570 are each iterative enhancements of the RX 460 and RX 470 GPUs AMD launched almost a yr in the past. Each Anandtech and Hot Hardware included the RX 570 of their opinions, and it broadly reveals the identical sample because the RX 580 — which is to say, efficiency is improved by ~12 p.c, the GPUs are quieter (because of improved cooling options relative to AMD’s reference designs on the RX 470 / RX 480), and so they throttle a lot much less. The flip aspect is that these GPUs do burn extra energy. Anandtech’s evaluate implies that the RX 570’s energy curve is a bit higher than the RX 580s, that means the hole between the inventory RX 470 and a customized, overclocked RX 570 is about 10 p.c smaller than the equal hole between a inventory RX 480 and an overclocked RX 580. Because the RX 570 can be clocked decrease than the RX 580, this suits our idea that Polaris is slamming into the highest of its frequency curve. We don’t understand how a lot headroom is left in these chips, however we’re pretty sure tapping it would burn bigger and bigger quantities of energy relative to measured efficiency enchancment.
The RX 570 is positioned between the upper-end of the GTX 1050 Ti’s worth vary and the underside of the GTX 1060 3GB’s. The 1050 Ti is decidedly outclassed by the RX 570, whereas the 1060 3GB is extra of a toss-up. As Eurogamer’s results present, there are comparisons the place AMD wins that match and others the place it loses.
The RX 460 is a bit totally different from its predecessor, in that it now has extra out there GPU cores and the next clock velocity.
The RX 460 had 896 cores, 56 texture mapping items, and 16 ROPS (896:56:16). The RX 560 is a 1024:64:16 design with a base clock of 1175MHz in contrast with the RX 460’s 1090MHz, for a achieve of eight p.c. Enhance clocks have additionally elevated by 6 p.c.
Between the extra cores and the upper clocks, the RX 560 needs to be a robust replace to the RX 460. AMD is claiming that the RX 560 needs to be on retailer cabinets by early Might with an SEP of $100 for a 2GB card. The RX 460 isn’t as quick as Nvidia’s GTX 1050 or GTX 1050 Ti, however the RX 560’s larger clocks and expanded core counts ought to assist AMD’s price range GPU compete extra successfully. If OEMs supply manufacturing facility overclocked playing cards, we might see the RX 560 unseating the GTX 1050 because the price range GPU of selection. It’ll additionally assist if 4GB playing cards find yourself within the $100 – $120 worth vary — at present the most cost effective RX 460 with a 4GB body buffer is $109 at Newegg.
The RX 550, aka Polaris 12
Lastly, AMD is delivery an RX 550 for the primary time, to anchor the sub-$100 market. AMD and Nvidia haven’t put a lot deal with this area for a number of years — most individuals who purchase on this worth bracket use an built-in GPU. AMD’s GPUs on this worth band have been based mostly on Cape Verde (GCN 1.zero) or Oland (GCN 1.x — it’s a variant between GCN 1.zero and 1.1, with some, however not all, of Hawaii’s options).
AMD hasn’t launched a lot details about the RX 550 but. We all know it’s constructed on a brand new GPU, codenamed Polaris 12, with a lift clock of 1175MHz, 512 cores, and 2GB of VRAM. The reminiscence bus continues to be 128-bit, and the RX 550 reportedly has 32 texture mapping items, or TMUs.
The largest issue within the RX 550’s efficiency might be its ROP depend. The R7 250X was considerably sooner than the R7 250 as a result of it fielded a 640:40:16 core versus a 384:24:eight core. If AMD makes use of 16 ROPs (512:32:16), the RX 550 ought to simply win previous the R7 250X. If AMD solely makes use of eight ROPS, efficiency predictions get deal murkier.
Both manner, it’s a lot sooner than AMD’s R7 250. This new GPU is being positioned as an entry-level gaming GPU, with HDMI 2.0b assist, HEVC and 4K playback functionality, and as being out there in low-profile designs for SFF type components the place your skill to improve your GPU could also be sharply restricted by area. It’s additionally an apparent try to win laptop computer designs, the place energy is at a premium.
AMD isn’t doing something essentially new with its RX 5xx refresh cycle, however each the RX 560 and RX 570 needs to be noticeably sooner than their predecessors, bettering the corporate’s aggressive stance in opposition to Crew Inexperienced.
The RX 550 isn’t more likely to be a serious revenue heart. However there are individuals who like PC gaming, however can’t afford to spend a lot cash on . In case you’re caught on an outdated R7 250, we count on the RX 550 to supply drastically higher efficiency for effectively underneath $100. Precisely how carefully it matches the RX 560 will rely upon what number of ROPs the GPU is configured with.
