Dasa 314 Posted February 6, 2019 (edited) https://www.kotaku.com.au/2019/02/radeon-vii-amd-australian-price-release-date-specs/ AMD have revealed this afternoon that their new card, which will ship in multiple configurations with a baseline of 16GB in HBM2 memory, 3840 stream proessors, Freesync 2 HDR support and 1TB/s of memory bandwidth, will be available in Australia from $1069. It's also been publicly revealed that the Radeon 7 will run at a boost clock speed of 1800Mhz Availability on all cards in Australia and New Zealand is unknown, although the Radeon 7 launches internationally February 8 Australian time. We'll update this post once a local release date is confirmed. AMD Radeon VII Unboxing & Preview The main die on the "Vega 20" MCM is the centrally located GPU die built on TSMC's 7 nanometer silicon fabrication process. Measuring 331 mm², this silicon packs 13.26 billion transistors, which is a similar transistor count to NVIDIA's TU104 graphics processor. The "Vega 20" GPU die features a 4096-bit wide HBM2 memory interface, which has double the bus width of "Vega 10". This means the GPU has to be surrounded by four memory stacks instead of two. On the Radeon VII, there are four 32 Gbit (4 GB) stacks built on a 10 nm-class node supplied by either SK Hynix or Samsung. We don't know the process node of the interposer, but given it was 65 nm for 4096-bit "Fiji", we can't imagine why it would change for "Vega 20". The interposer has no logic of its own and draws no power for itself. Its only purpose is to provide miniaturized wiring between GPU and memory stacks, and as such, there's nothing to be gained by changing its fabrication process if the desired wiring density has been achieved. A metal-reinforcement brace runs the periphery of the fiberglass package substrate to distribute mounting pressure from the cooler. AMD has used conventional-looking thermal pads over the VRM MOSFETs, which are somewhat reusable. The GPU interface is a whole different story. Defying conventional logic, AMD went with what clearly feels like a high-conductivity thermal pad between the vapor-chamber base and GPU instead of thermal grease. We believe this to be a strip of Hitachi TC-HM03, a high-density thermal pad with graphite strands and a rated conductivity of 25-45 W/m·K, which is higher than the typically 12.5 W/m· K offered by certain diamond-based high-viscosity pastes. Going by the lengths they have gone with the cooling I am guessing they are once again pushing the clocks as hard as they can to try compete. That or 7nm just runs hot so it will be interesting to see if there is any overclocking head room left and just how much power it draws. Considering the RTX 2080 which will be priced similar only needs 6pin+8pin power vs 8+8 I think it is safe to assume that despite the 7nm process it will still be less efficient but then you do get twice as much memory.

Oh yeah... it's still the same inefficient uarch, only now it's on race fuel. Navi will be mid-range first and... not sure what a Navi 20 form will take. but it needs to be good Don't even know if AMD will be splitting it's GPU architectures between compute and graphics... probably can't afford it. 1 Share this post Link to post Share on other sites
Dasa 314 Posted February 7, 2019 Wonder how well my good old universal GPU block would fit. Had to make a copper shim for it to fit the 7970. looks like a fairly large area to cover with all that HBM2 and if they used a pad I cant help but wonder how flat it is.

Dasa 314 Posted February 8, 2019 (edited) Kinda funny that Nvidia breaks there idle power use just as AMD finally get's it right with low power use for multiple monitors and when watching video for once. Just a shame it is still running 250-350w load Looks like temperature is the main thing holding back clocks on this card and problems with the drivers for overclocking with auto OC hitting up to 2150MHz on dry ice at -25c and close to 2000MHz for techpowerup with improved tim, increased mount pressure and the stock HSF. It will be interesting to see what it can do on water once software improves. Looks like there is virtually no stock available at this point. Anyway here is a few reviews that show on average it is ~10% slower than RTX 2080 but in some things it pulls infront. https://www.techpowerup.com/reviews/AMD/Radeon_VII/ https://www.gamersnexus.net/hwreviews/3437-amd-radeon-vii-review-not-ready-for-launch https://www.pcper.com/reviews/Graphics-Cards/AMD-Radeon-VII-Review-Supercharged-Vega https://www.techspot.com/review/1789-amd-radeon-vii/ https://www.tomshardware.com/reviews/amd-radeon-vii-vega-20-7nm,5977.html https://www.anandtech.com/show/13923/the-amd-radeon-vii-review https://www.tweaktown.com/reviews/8894/amd-radeon-vii-review-team-red-back-enthusiast-gpus/index.html Edit: big list of reviews https://www.reddit.com/r/Amd/comments/ao05xo/radeon_vii_reviews_megathread/ Edited February 8, 2019 by Dasa Share this post Link to post Share on other sites
Jeruselem 850 Posted February 8, 2019 I think people with current Vegas and RTX cards should just keep their current cards, not much a gain in performance. Share this post Link to post Share on other sites

Dasa 314 Posted February 8, 2019 If it gets some availability and the price settles in then it is probably competitive and I believe that on water it will be able to pull in front. I am concerned that the 16GB high speed memory is just what the miners have been waiting for though and may kick it all off again. I find myself leaning towards a secondhand 1080Ti for $750 But would love to be one of the first to stick it on water assuming I could find a way to tack on my old block.

gamble 97 Posted February 8, 2019 might as well remove the games or have the option to, reduce the price by 100 and let the miners and gamers fight it out over msrp... 1080 ti is kinda a steal now second hand. 2080 and VII are just too high priced and only makes sense if buying new. VII going to use more power and have some driver issues it appears from the reviews for certain games. Im always rooting for AMD, maybe Navi will look better for the mid range.

Dasa 314 Posted February 8, 2019 (edited) This review looks into undervolting and overclocking showing performance with both. Once undervolted performance remains much the same but efficiency and noise is improved significantly to the point where performance per watt is competitive with Nvidia. https://translate.google.com.au/translate?sl=auto&tl=en&u=https%3A%2F%2Fwww.computerbase.de%2F2019-02%2Famd-radeon-vii-test%2F2%2F%23abschnitt_undervoltage_ist_der_eigentliche_koenig_der_radeon_vii_uv Edited February 8, 2019 by Dasa 1 Share this post Link to post Share on other sites

Nich... 782 Posted February 9, 2019 For the same price I'd want something better than 'within 10% slower than the competition', TBH. Kinda weird if performance is the same when undervolted - and why that wasn't more of the default setup. Share this post Link to post Share on other sites

I guess there sample didn't exactly lose the silicon lottery and by overvolting significantly they can increase the % of usable cores. Share this post Link to post Share on other sites

Jeruselem 850 Posted February 12, 2019 https://www.tomshardware.com/news/amd-radeon-vii-lacks-uefi-support,38592.html According to TechPowerUp's research, the Radeon VII's reference BIOS doesn't come with UEFI support or a GOP (Graphics Output Protocol) driver for the matter. The GOP driver is important as it's the component that's responsible for display duties during the pre-boot process. For the Radeon VII to work properly, the user must have CSM enabled, which means losing Microsoft's Secure Boot feature and potentially increasing boot times during cold boot. From a performance perspective, the Radeon VII should perform the same whether it's using a non-UEFI BIOS or UEFI GOP BIOS. 1 1 Share this post Link to post Share on other sites
