we've got two quick news items today that didn't deserve their own separate videos one is Andy's n there's a bunch of news on that at my sort of IDF next door anyway and then Nvidia now has a GTX 10 CC with 3 gigabytes of VR am officially this time not just a rumor so we'll be talking about that in a second first this content is brought to you by i buy power and their new element gaming PC which has the red LED underglow arc LED fans a large tempered glass side window so you can look at all of the LEDs first off with AMD the Zen architectures of course the new architecture coming up it is replacing sort of the vchera bulldozer excavator all those chips are going to be AOL as zen roles in the main ship that we've seen a few times now and was shown officially at the sunnyvale while san francisco event by the sunnyvale company it is the eight-core 16th red chip so it is an smt chip it's got simultaneous multi-threading which is basically what Intel hyper-threading as they've sort of rebranded it and changed a few things but same idea where you've got eight physical cores 16 threads that was on display at this event and in and II showed a 40-percent IPC gain instructions per cycle which is something they've needed to compete in performance with Intel and hopefully reach parity if not exceed Intel's current gen performance so that was shown the forty percent gain there were also some architecture unveils for Zen and this was demonstrated through the eight core 16th red chip and through a server chip called Naples which is a 32 core 64 thread chip that is a server chip again it's not something you'll use in a gaming PC they had two of those in a server board so sort of like a old skull trial set up so I was just server 22 cpu motherboard so that was demonstrated and some of the architecture information revealed for summit ridge which is the eight core 16 thread one that we're mostly looking at increases the issue with an execution resources by 1.5 x over excavator and a 1.75 x increase in the instruction scheduler window over excavator as well single thread performance improves by greater instruction level parallelism and AMD still drives a big focus on integer units so this is something that Andy's always been pretty big on energy units over a floating-point obviously there's still floating point half the block diagram is floating point but integer units specifically were shown at this event and we can see that there are four al use to AG use and the latter of which pipe into the load/store queue Zen can perform two loads and one store with each cycle and caches in a 32 k 8 way d cash the FPU side of the chip runs to multiplying two ads for floating-point operations with a single scheduler flanked by the FP rename and FP register file we'll talk about this more in the future probably in our design review once we get there and explain what all this stuff means cash is mostly unified now so there's eight megabytes of l3 cache shared and then the l2 cache is also unified for instruction use so that is a big part of these IPC gains caches it plays a huge role on TP performance especially with certain types of modern games so that's one of the big news items it is 40 nanometer FinFET same as sort of the Polaris lineup and that means that all the same power efficiency gains native to that process node are going to be yielded pretty much in Zen clock gating is still there and AMD also showed a clock for clock blender performance which is a rendering and animation tool so they showed clock for clock performance versus an i7 broadwell each ship at eight cores 16 threads so same corn thread count obviously completely different architectures so not perfectly linear and clockwork locked not necessary perfectly linear but andy claimed that they were outperforming intel in this specific application with blender presumably for render times finally summit ridge will launch on the am for platform which is brand new it will be replacing the am3+ platform and the FM platform so ap use will no longer be on their own platform which is actually a really good thing probably as long as they all function fine but the good part of it is if you buy one motherboard you can use it for either AP use or Zen CPUs as long as it's 7-10 ApS so obviously the upgrade pathway is clear if you wanted to kind of my great one board down and use it for an eight you set up then you could do that so that is am for Bristol Ridge will function an am for if you have read about that architecture that processor and system integrators will be shipping am for systems starting in the second half of this year very soon and hopefully we'll be reviewing it so and these moving to am for which has modern support for pcie gen3 USB 3.1 and ddr4 native support and say to express support so it's completely updated nvm ease also they're all those issues with am3+ will be resolved at am for the next bit of news is about the GTX 1063 gigabyte card we don't have one yet nvidia is not sampling media this time so I've got some on the way through board partners and we'll be reviewing it but basically it's a three gigabyte card it's not the same as the 1060 those specs are changed a bit so they've disabled one sm or simultaneous multiprocessor you look at a block diagram with the card for the 1066 ii goodbye you'll see 10 SMS and one of those has effectively been turned off so that means with 128 cores per SM we go from 1280 cuda cores on the 1066 gigabyte down to 1152 cuda cores on the three gigabyte card so that's one of the big changes that will impact performance certainly the clock rate is the same on the three gigabyte and six gigabyte models and that's the sort of 1517 hundred megahertz clock rate that we've talked about before other than this frame buffers different TMU count is down a bit coup de coeur count is down a bit clock rates the same and the frame buffer is half so that's the main update with this card in the past the most we've seen these vm changes impact performance have been in very specific applications Assassin's Creed syndicate black ops 3 with certain settings Mirror's Edge catalyst with certain settings things like that not every game will reflect the change but some of them do I don't know if this is sort of correlation is not causation thing but often gameworks titles we see a change so that's something we'll be talking about and video claims a five percent Delta between the three and six gigabyte cards but a fifty dollar price gap I'm not sure how it'll actually work because you're still removing ten percent of the cores so that ten percent with a five percent reduction seems weird so we'll be testing that and Nvidia is also claiming claiming a performance gain over am these are x48 gigabyte card of ten percent so will validate that as well but if they're not sampling so I'll make sure we get some whether I have to buy it or otherwise availability will begin in the next couple weeks for the three gigabyte card it will be two hundred dollars MSRP we'll see what it actually lands at but that's fifty dollars reduced an MSRP from a 60 k by model and that's that's really all there is to it so we'll see we'll see how it works the driver update was pushed today so that will make cards function once they're out there board partners are starting to send them out so we'll have news for you on that and on Zen as more news is available next week there will be a Zen update as well so we'll try and post some information on that it will be about architecture again thank you for watching as always pay channeling cholesterol video for information hit the links in the description below we've got articles on both of these news items already subscribe for more I'll see you all next time
