Thanks for the info, huhn!

i can re test this maybe next week sorry.
Yes this part of the VRAM is for Rendering the Desktop but you hardly realize this loss and you get a lot of benefits from it and the (LDDM) WDDM DWM Render Model since it was introduced with Longhorn back then in efforts to gain Apples GPU Desktop Efficiency Level.

Though the overall Memory usage up today is dependent on more factors like if you use Variable Refresh or a fixed Refresh Rate 10bit 8 bit hdr or not since Windows 8.1 and 10 there is no real differentiation anymore and it's a fully fixed part integrated and in Windows 10 it drives the whole UWP experience between Windows Devices

No 3rd Party Media Player yet uses it fully efficient on Windows 10 and it's many Display changes yet but also drivers are still in a changing stability state

There is no 3rd Party Player yet even existing with a full DX 12 Render Pipeline not even a simple ported one

Then it happens only with madVR not EVR

No surprise EVR is tuned for System Resource efficiency ontop of DWM not Extreme Quality

UHD playback Vram usages using a UHD source HDR processing is disabled in madVR because EVR doesn't know what HDR is:
lavfilter 0.68.1
mpc-hc 1.7.10.252
clip sony 4K HDR Camp
gpu 960 with a boost clock of 1430 mhz

copyback
madVR GPU queue at 4 1547-1750 mb
EVR CP queue 4 1922-2000 mb

native
madVR GPU queue at 4 present queue 3 1600 mb BLACK SCREEN in full screen.
EVR CP queue 4 1780 mb

a difference of 100 of mb each time are pretty normal.
get more than 2 gb that's all i have to say to this.

the default GPU queue for madVR is 8 which is unusable for UHD with 2 GB Vram. the default GPU queue for EVR is 5 or 6.

GPU usages was ~70% with both EVR and madVR. madVR was at default except queue and FSE mode.

Notebookcheck has a DXVA checker screenshot from the Kaby Lake HD650 Graphics

HEVC Main 10 as well as VP9 Profile 0 and 10 bit are now decoded up to 8k.

Nice info for Kaby from Anandtech.

It's all Media update the Kabylake update.
The gain of CPU is the gain of MHz due to the advanced 14+ nm process.
The GPU is the same Gen 9.

But the media capabilities are impressive.

The fastest Kabylake processor Core i7 7700K will try to stand against the 8 core/ 16 thread ZEN in the early 2017.

It has no chance at all, it will be eaten for breakfast by ZEN in all apps besides the heavily optimized AVX/ AVX2 ones.

Of course Kabylake has an iGPU inside where ZEN 8 core/ 16 thread will be a CPU only SoC.

But that's a problem of Intel to release 8 core CPUs without iGPUs for mainstream Core i7 and not for the High-End Desktop (HEDT) terribly expensive systems only.

the marketing from intel is terrible in general.

they have mainstream processors without an iGPU but they usually cost extra making them pointless.

so there is absolutely no reason to buy a mainstream CPU without iGPU. you can use the hardware decoder or the iGPU just in case you need it.

AMD ZEN can spare a lot of silicon making them a lot cheaper in production and the TDP will look better on paper.

Didn't understand a word of what you've written, but OK...Maybe others do.

I know I always enjoy reading your off topic delusional AMD fanboy posts. Please keep it up.

Zen will lose in 99% of games because it cannot compete with the IPC+clockspeed of Kabylake. Just one example where you are wrong.

I'm not so sure about games like you.

Because new games using Vulkan and DX12 tend to use more and more cores and threads, it will be an interesting fight with games.

In office applications, production applications, rendering, general purpose benchmarks and Cinebench it will vanish Kabylake for sure.

Doesn't matter really. Over 99% of the games will still use DX11 or even DX9 by next year. And for non gaming apps there is lots of stuff where you don't see improvements over 4 cores. It would be very very sad if a 8 core CPU can't demolish a 4 core CPU in Cinebench. This isn't a fanboy thread for AMD CPUs, you may search for another place to discuss this further.
