At present, AMD has no support for Microsoft's DXR (DirectX Raytracing) API or Vulkan-RT. However, you do need to decide whether or not you want to be able to play around with the new and upcoming ray tracing games. Generally speaking, I expect the RX 5700 will be faster in many games, thanks to its additional 2GB of memory and generally higher specs. Both sell for $349, though the 2060 can be found for slightly less than that now. With Nvidia's updated RTX lineup and AMD's reduced launch pricing on the RX 5700 line, the direct competition for the RX 5700 is the GTX 2060 (non-Super). Sure it's $50 extra, but that's less than the price of a typical game, and you'll get to enjoy the added performance on every game you play. If you want a custom factory overclocked RX 5700, I'd just bump up to the 5700 XT first. Those may cost a bit more, depending on the particular model, overclock, and other amenities, which sort of flies in the face of the 5700's lower pricing. If you're not a fan of blowers (*cough*), AMD's board partners will of course have axial fans and open air designs available, including models with factory overclocks. That in turn means less fan noise, and at stock sitting in an enclosed case, the noise of the RX 5700 fan wasn't really audible. The good news is that unlike the reference Vega cards, the RX 5700 has a much lower TBP (Typical Board Power) of just 175W, which in turn means the fan won't need to spin nearly as fast. It looks similar to the RX Vega cards, but with an aluminum shroud and no dots, with the Radeon logo shifted around a bit. Unlike the 5700 XT, the vanilla RX 5700 sports a more traditional blower design (sans dent). Or in other words, the RX 5700 cards likely won't hit the same clockspeeds as the 5700 XT, no matter how hard you try to overclock.ĪMD provided reference models of the RX 5700 XT and RX 5700 for testing. For newer manufacturing nodes like TSMC's 7nm, the gap is more likely to be larger. Depending on how intensive and accurate the binning process is-and how mature the manufacturing process is-the gap between the 'best' and 'worst' functional chips from a wafer may be relatively small. Meanwhile, the functional but perhaps not quite as good chips are harvested and sold as lower tier parts. Thus, the best chips usually get sold as the fastest, most expensive parts-the Core i9-9900K, Ryzen 7 3800X, or RX 5700 XT. Chips with impurities or errors don't fully work, so modern processors build in redundancies and some portions of the chip can be disabled to produce a working chip-but one that's not as fast as a fully enabled chip.Īfter each wafer gets cut into individual chips, each is tested to determine how good it is in a process called binning. My understanding is that chips from the center of the wafer tend to be 'better' than those near the edge, so they may require less voltage to hit the same clockspeed, or they may run at higher clockspeeds at the same voltage. There are impurities in the wafers used for making CPUs and GPUs, and these can lead to errors or differences in performance characteristics. Modern microchips are made using large (300mm) silicon wafers, cut from a large silicon crystal cylinder.
