AMD launched a complete refresh cycle of its midrange graphics playing cards at this time. 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 what’s modified for these chips, and what the updates imply for players 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 practically a yr in the past. Each Anandtech and Hot Hardware included the RX 570 of their critiques, and it broadly exhibits the identical sample because the RX 580 — which is to say, efficiency is improved by ~12 p.c, the GPUs are quieter (due to 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 overview implies that the RX 570’s energy curve is a bit higher than the RX 580s, which 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. For the reason that RX 570 can be clocked decrease than the RX 580, this matches our principle 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’ll 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 obtainable GPU cores and the next clock velocity.
The RX 460 had 896 cores, 56 texture mapping models, 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 acquire of eight p.c. Enhance clocks have additionally elevated by 6 p.c.
Between the extra cores and the upper clocks, the RX 560 ought to be a powerful replace to the RX 460. AMD is claiming that the RX 560 ought to be on retailer cabinets by early Could 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 finances GPU compete extra successfully. If OEMs supply manufacturing unit overclocked playing cards, we might see the RX 560 unseating the GTX 1050 because the finances GPU of selection. It’ll additionally assist if 4GB playing cards find yourself within the $100 – $120 worth vary — presently the most affordable 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 give attention to this house 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 remains to be 128-bit, and the RX 550 reportedly has 32 texture mapping models, or TMUs.
The largest issue within the RX 550’s efficiency might be its ROP depend. The R7 250X was considerably quicker 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 a very good deal murkier.
Both manner, it’s a lot quicker than AMD’s R7 250. This new GPU is being positioned as an entry-level gaming GPU, with HDMI 2.0b help, HEVC and 4K playback functionality, and as being obtainable in low-profile designs for SFF type components the place your means to improve your GPU could also be sharply restricted by house. It’s additionally an apparent try to win laptop computer designs, the place energy is at a premium.
AMD isn’t doing something basically new with its RX 5xx refresh cycle, however each the RX 560 and RX 570 ought to be noticeably quicker than their predecessors, bettering the corporate’s aggressive stance in opposition to Crew Inexperienced.
The RX 550 isn’t prone 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 previous R7 250, we anticipate the RX 550 to supply drastically higher efficiency for nicely beneath $100. Precisely how carefully it matches the RX 560 will rely on what number of ROPs the GPU is configured with.
