so there's been a lot of speculation in regards to Amy's next-generation CPU and GPU architectures how powerful will they be how efficient how affordable we're going to answer all those questions in this video so stay tuned recall AMD's previous GPU naming scheme the southern islands which was based on the raid on HD 7000 series included graphics cards such as the seventy eight seventy seventy nine fifty and seventy nine ninety you may recall the codename Tahiti used to describe in particular the seventy nine fifty and seventy nine seventy these were later rebranded as the r9 280 and 280x respectively the Hawaii GPU famous for its extraordinary thermal output and inclusion into the 292 90 X and 390 series cards was a part of AMD's volcanic islands family now in this case AMD has decided to change things up a bit originally dubbed the Arctic Islands ambe's next generation graphics cards will include GPUs named after stars and constellations hence the familiar name Polaris the Polaris family will include the next phase of our the RX 402 here graphics cards similar to r7 470 + r9 490 later this year each card will include hdmi 2.0 a support which on top of supporting 4k up to 60fps will also include HDR support and higher contrast values and games and movies the cards will also feature h.265 support which will allow 4k content encoding it up to 60fps as well h.265 will aid in the cards ability to interpret 4k footage in particular by eliminating color washing and increasing complexity area control basically just makes your image look a little better DisplayPort 1.3 will also be a standard on these cards Polaris is also an extremely efficient 14 nanometer design a recent AMD event showcased a prototype graphics card equipped with a Polaris GPU running star wars battlefront and 1080p with medium settings at 60fps it only drew 286 watts of power compared to the 140 watts required by Nvidia's GTX 950 for the same experience that's a 61% increase in efficiency between the two cards impressive AMD hopes to bring virtual reality to the forefront in gaming and if noted that their minimum VR Spectre graphics cards will likely be under the 350 US dollar range currently the GTX 970 and r9 390 graphics cards are the bare minimum for VR gaming so expect Polaris to replace and improve upon the 390 at around the same price point the performance figures for even the most powerful cards in the Polaris lineup are unfortunately still entirely unknown though the r9 nano and fury X will likely be superseded in terms of performance and performance per watt now what do we know about Zen if you aren't familiar then is the code name given to the next-generation microarchitecture for AMD CPU lineup it will replace the excavator architecture which was the last revision of the bulldozer family made famous most notably by the FX 6300 all Zen CPUs will utilize the am for socket and be built on a 40 nanometer process a significant step forward from the 32 and 28 nanometer processes of the FX CPUs and a series ap use only ddr4 will be supported by Zen although the next generation ap use which will also use the unified am for socket will support both ddr3 and ddr4 in terms of performance the IPC or instructions for clock which is a measure of CPU performance of a single Zen core has improved by 40 percent over that of an excavator core according to AMD for comparison Intel's newest CPU architecture skylake received only a 6 percent IPC increase from Haswell the 4000 series and a 3 percent increase from Broadwell the 5000 series an IPC is typically expressed as a ratio that is a percent increase or decrease from a baseline value while not always accurate an IPC can be used to directly estimate scores and CPU intensive tasks such as Cinebench r15 for example given only a 6 percent IPC increase from Haswell to skylake in a single core Cinebench r15 score of 120 for the Haswell processor one should expect the skylake CPU single core score to end up around 127 all other things equal these estimates however it can be inaccurate if different generations of RAM are used between the platforms in question or if core count or core clock speeds are different so how will then perform head-to-head against Haswell or skylake CPUs well if we take AMD's claim at face value that Xen will perform about 40 percent better than excavator this means that it will perform about 65 percent better than bulldozer and CPU intensive tasks however Intel's Ivy Bridge IPC was already 55 percent higher than bulldozers when both architectures were released in 2012 from Ivy Bridge to Haswell IPC increased by 11 percent this means that haswell's IPC is roughly 66 percent higher than bulldozers and according to this math literally on par with Xen 66 percent over 65 percent I should note that other sources list smaller IPC gains between Ivy Bridge and Haswell the estimates range anywhere between 5% and 15% so this means the Sens per core instruction speed could be anywhere between 7% slower and 3% faster than haswell's in terms of skylake its IPC improvement over Haswell was very small about 6 percent of you recall from a bit earlier this means that in relation to skylake Xen could have an IPC anywhere from 13 to 3 percent lower than sky lakes it's actually not bad this in combination with simultaneous multithreading similar to hyper threading on Intel side up to 64 PCIe lanes and core counts up to even 16 as speculated by a few sites should pose quite a threat to intel's current lineup and it's about time this could leave big impressions on the microprocessor industry some serious competition from AMD could once again spark the consumer CPU races from the early 2010 decade and prompt a various price cuts all across the industry ddr4 prices could continue to fall and slightly compatible motherboards will likely dip further in price to better compete with AMD's likely already competitive price point both Polaris and Xen look very promising from my personal perspective here in the studio but I want to hear from you be sure to let me know in the comments below if you will consider products from either of these lineups
