AMD within the official press-conference dedicated to gaming show E3 2019, introduced the Radeon RX XT and 5700 Radeon 5700 RX is the first commercially available members of the line Navi on the architecture of the RDNA. They will go on sale July 7 and will be offered at a price of $450 and $380 respectively. Everyone was waiting for Navi lower of cost (rumors spoke of the range of $200-300), but in comparison to competitors Nvidia new items still look quite attractive.
the design features of the chiller and the power subsystem innovations
On the specifications and technical details of new products will be discussed below, and now the most interesting – compare the performance of these graphics cards to the Nvidia counterparts.
the First slide is dedicated to 5700 Radeon RX XT: in most games with maximum graphics settings, it bypasses the performance of GeForce RTX 2070.
Radeon RX 5700, in turn, on average, about 10% ahead of the GeForce RTX 2060 – with the same graphics settings and same resolution.
the Main characteristics of the Radeon RX XT 5700 became known the day before yesterday, and today, we can say, they were right. Video card has 40 compute units, and 2560 stream processors and 256 texture units and 64 raster.
the base GPU frequency is 1605 MHz, but it is, by itself, may increase. And now there are two such levels: the game – up to 1755 MHz and the Boost to 1905 MHz. Memory GDDR6 amounted to 8 GB, it's paired with a GPU bus with a bit width of 256 bits. The memory frequency is 14 GHz – exactly like the Nvidia GPU Turing TU104. The maximum performance on operations with single precision TFLOPS 9.75.
To supply additional power provided by two octal connector, the value of the TBP (Total Board Power) – 225 watts.
Radeon RX 5700, as you can tell from the title, is a lightweight variant of the older model. There is also a 256 texture and 64 raster block, but less compute units – 36 and, accordingly, fewer stream processors – 2304. And below frequency: base – 1465 MHz, slot – 1625 MHz, Boost – 1725 MHz.
On the part of the memory corresponds to the older model. As for performance, it is on operations with single precision it is of 7.95 TFLOPS. For supplying additional power supply has two connections – eight - and restistrey. Value TBP – 180 watts.
in General, for models of the GPU which are produced according to the process of 7 nm, the value of TBP is somehow not impressive. For comparison, the same TDP GeForce RTX 2070 – 170 W, and this despite the fact that the latter is at 12 nm FinFET process technology. However, the power consumption of these models is better to compare in real-world applications, not on paper.
