So if you don't care about noise (which varies by manufacturer), price (given that one is significantly older prices vary significantly) or power-consumption, the r9 270x is probably better. note - I paid $50 for a used r9 270x 4gb, therefore I feel the value section should be eliminated for old cards. I get roughly the same fps in unigen benchmarks using both cards. The 270x usually gets one or two FPS better, but really these cards are about the same.
Yeah it'll be a case by case basis between which is better. But I wouldn't be surprised if the 270x starts to fall behind with the newer titles that are coming out. They definitely trade blows between titles with 1 winning here and 1 winning there by actually pretty big margins sometimes 15%. The 270x would probably win out in GTA V too if you maxed it to where both cards were getting under 60fps.
Well i'm basing mine from experience. Never Got past 40FPS when playing Metro Redux using the RX460. When I went back to my old card R9-270x, i hit 50-55ish again. So i really dunno what i'm gonna do with the extra card my sister gave me. But eitherway, i stand by what i observed and experienced
Who gives a shit about synthetic benchmarks and comparing specs of 2 cards that have DIFFERENT architectures. It's like comparing shading units to cudacores between AMD and Nvidia. Or comparing cudacores in a 670 to a 970, even the 1050 ti and 950 have nearly identical specs, but the 950 gets smoked. It's not the same. The delta between a 270x and 370 is probably about 5%-8% in real game benchmarks, not firestrike the performance is as identical as it gets. Further proof, there's charts for the 2 cards in the tomshardware link. Please don't just site specs and send me solid performance charts if you're going to say the 270x isn't identical and is a lot better. They trade blows winning between titles. http://www.tomshardware.com/reviews/amd-radeon-rx-460,4707-4.html https://www.youtube.com/watch?v=aNPp_ZC2FQA
The architecture isn't quite the same. The RX 460 has the same, if not better, performance in games. Check reviews. Raw data doesn't mean jack in the grand scheme of things. By that I mean, if you compare two cards, you need to understand that base on the generation, more is better. If you compared a GTX 660 to a GTX 580, you'd find that they're equal in almost every way. How's that though? The GTX 660 as 960 CUDA cores versus the GTX 580 having only 512. Different architecture. Long story short, the RX 460 is actually equal to the 270X. Reviews prove this.
NO
Definitely not. Higher memory bandwidth 179.2 GB/s vs 112 GB/s Around 60% higher memory bandwidth Higher pixel rate 33.6 GPixel/s vs 19.2 GPixel/s More than 75% higher pixel rate More render output processors 32 vs 16 Twice as many render output processors Better fire strike factor score 62.77 vs 46.49 More than 35% better fire strike factor score More shading units 1,280 vs 896 384 more shading units More texture mapping units 80 vs 56 24 more texture mapping units More compute units 20 vs 14 6 more compute units
Nearly identical cards in terms of performance.
