The AMD Radeon VII Review: An Unexpected Shot At The High-End
by Nate Oh on February 7, 2019 9:00 AM ESTFinal Fantasy XV (DX11)
Upon arriving to PC earlier this, Final Fantasy XV: Windows Edition was given a graphical overhaul as it was ported over from console, fruits of their successful partnership with NVIDIA, with hardly any hint of the troubles during Final Fantasy XV's original production and development.
In preparation for the launch, Square Enix opted to release a standalone benchmark that they have since updated. Using the Final Fantasy XV standalone benchmark gives us a lengthy standardized sequence to utilize OCAT. Upon release, the standalone benchmark received criticism for performance issues and general bugginess, as well as confusing graphical presets and performance measurement by 'score'. In its original iteration, the graphical settings could not be adjusted, leaving the user to the presets that were tied to resolution and hidden settings such as GameWorks features.
Since then, Square Enix has patched the benchmark with custom graphics settings and bugfixes to be more accurate in profiling in-game performance and graphical options, though leaving the 'score' measurement. For our testing, we enable or adjust settings to the highest except for NVIDIA-specific features and 'Model LOD', the latter of which is left at standard. Final Fantasy XV also supports HDR, and it will support DLSS at some later date.
Moving on to Final Fantasy XV, the Radeon VII's showing here is one of the least ideal scenarios. The game has historically performed well on NVIDIA hardware, so the RTX and GTX performance levels are well-known. With a lot of ground to cover from RX Vega 64's starting point, the Radeon VII does well in pushing up to a 34% speedup at 4K and 28% at 1440p. While that is enough to overtake the reference RTX 2070 at 4K/1440p, the RTX 2080 and GTX 1080 Ti FE remain out of reach.

The first part of your conclusion describes what this product is. It is surprising to see this card's existence at 7nm, a Vega with 16GB of HBM2.It appears to me that AMD/TSMC is learning the 7nm process for GPUs/CPUs and the few chips they produce be sold as a high end part (as the volume/yields is being improved).
AMD really shot high with its power consumption (clocks) and memory to reach the pricing of the GTX 2080.
However, I haven't seen a publisher to show undervolting results. Most Vegas perform better with this tweak.

I think you are being a little too critical of this card. Considering it’s an older architecture, it’s impressive it’s in the 2080’s ballpark.And for those like me that only care about Frostbite Engin based games, this card is obviously a better option between the two cards at the same price.
You also ignored the overclockong potential of the headroom given by moving to 7nm

"You also ignored the overclockong potential of the headroom given by moving to 7nm"Unfortunately it seems to be already overclocked to the max on the core. VRAM has some headroom but another couple of hundred MHz isn't going to do wonders considering the already exorbitant amount available.

"I think you are being a little too critical of this card."Unless someone can take advantage of the non-gaming aspects of it, it is dead in the water at the current price point. There is zero reason to purchase a card, for gaming only, that uses more power and creates vastly more noise at the same price point of one that is much more efficient for gaming purposes. And, the only way to tame the noise problem is to either massively undervolt it or give it water. Proponents of this GPU are going to have to show that it's possible to buy a 3 slot model and massively undervolt it to get noise under control with air. Otherwise, the claim is vaporware.
Remember this information? Fiji: 596 mm2 for $650. Vega 10 495 mm2 for $500. Vega 20 331 mm2 for $700.
Yes, the 16 GB of RAM costs AMD money but it's irrelevant for gaming. AMD not only gave the community nearly 600 mm2 of chip it paired it with an AIO to tame the noise. All the talk from Su about improving AMD's margins seems to be something that gamers need to stop lauding AMD about and starting thinking critically about. If a company only has an inferior product to offer and wants to improve margins that's going to require that buyers be particularly foolish.

I wouldn't call the 16GB irrelevant. It trumps the 2080 in the two most demanding 4K titles, and comes relatively close in other ultra high resolution benchmarks.It could be assumed that's a sign of things to come as resolutions continue to increase.

"It could be assumed that's a sign of things to come as resolutions continue to increase."Developers adapt to Nvidia, not to AMD. That appears to be why, for instance, the visuals in Witcher 3 were watered-down at the last minute — to fit the VRAM of the then standard 970. Particularly in the context of VRAMgate there was an incentive on the part of Nvidia to be certain that the 970's VRAM would be able to handle a game like that one.
AMD could switch all of its discreet cards to 32 GB tomorrow and no developers would bite unless AMD pays them to, which means a paucity of usefulness of that 32 GB.

This offering is truly a milestone in engineering.The Radeon VII has none of the RTX or tensor cores of the competition, uses markedly more power *and* is built with a half node process advantage and still, inexplicably, is slower than their direct competitor?
I've gone back and looked, I can't find another example that's close to this.
Either TSMC has *massive* problems with 7 nm or AMD has redefined terrible engineering in this segment. One of those, at least, has to be at play here.

The RTX and Tensor die area may help with power dissipation when it's shut down, in terms of hot spot reduction for instance. Vega 20 is only 331 mm2. However, it does seem clear enough that Fiji/Vega is only to be considered a gaming-centric architecture in the context of developers creating engines that take advantage of it, à la DOOM.Since developers don't have an incentive to do that (even DOOM's engine is apparently a one-off), here we are with what looks like a card designed for compute and given to gamers as an expensive and excessively loud afterthought.

There is also the issue of blasting clocks to compensate for the small die. Rip out all of the irrelevant bits and add more gaming hardware. Drop the VRAM to 8 GB. Make a few small tweaks to improve efficiency rather than just shrink Vega. With those things done I wonder how much better the efficiency/performance would be.
