AMD Radeon R9 290X Review, Design and Testing Performance

It is no secret that the announcement of a new family of graphics cards AMD Volcanic Islands with sufficiently low prices recommended flagship surprised not only users but also its main competitor. So, the answer – AMD Radeon 290X R9 – 549 U.S. dollars, the decline in prices for two of the three “top” of cards from NVIDIA. At the end of October 2013 recommended cost model for NVIDIA GeForce GTX 780 has been reduced from 649 to 499 U.S. dollars, and the version of the NVIDIA GeForce GTX 770 – from 399 to 329 U.S. dollars. Only flagship – NVIDIA GeForce GTX TITAN – was unmoved with its price tag of 999 U.S. dollars.

AMD Radeon R9 290X Review 02 AMD Radeon R9 290X Review, Design and Testing PerformanceLet’s see what made competitor so respond quickly to release AMD Radeon R9 290X. After the announcement itself flagship graphics card with a price tag of U.S. $ 549, though a surprising event, but without an appropriate level of performance is not able to stir up the market so.

Graphic core novelties called AMD Hawaii XT quite logically performed on 28-nm microarchitecture AMD Graphics Core Next and consists of four building blocks called «Shader Engine». Note also grown since AMD Radeon HD 7970 volume of L2 cache and 384 KB to 1 MB, and the bandwidth of L1-L2 with 700 GB / s up to 1TB / s.

Another advantage of AMD Radeon R9 290X is increased up to 512-bit memory bus. It is possible to raise the capacity by 20% compared to the AMD Radeon HD 7970, which, taking into account the effective memory frequency 5000 MHz, are now able to pass an impressive 320.0 GB of information per second.

As a result, TTX trends in comparison with other models as follows:

AMD Radeon R9 290X Review 04 AMD Radeon R9 290X Review, Design and Testing PerformanceAMD Radeon R9 290X is much greater than junior graphics computing power, so the most interesting is to compare its performance with competitors from the company NVIDIA, but we’ll discuss this in the relevant section, and yet continue to get acquainted with the features of the new flagship.

As it became known, AMD Radeon R9 290X received an updated mechanism for monitoring energy consumption and overclocking – AMD PowerTune.
