Grand Theft Auto V
The highly anticipated iteration of the Grand Theft Auto franchise hit the shelves on April 14th 2015, with both AMD and NVIDIA in tow to help optimize the title. GTA doesn’t provide graphical presets, but opens up the options to users and extends the boundaries by pushing even the hardest systems to the limit using Rockstar’s Advanced Game Engine under DirectX 11. Whether the user is flying high in the mountains with long draw distances or dealing with assorted trash in the city, when cranked up to maximum it creates stunning visuals but hard work for both the CPU and the GPU.
For our test we have scripted a version of the in-game benchmark. The in-game benchmark consists of five scenarios: four short panning shots with varying lighting and weather effects, and a fifth action sequence that lasts around 90 seconds. We use only the final part of the benchmark, which combines a flight scene in a jet followed by an inner city drive-by through several intersections followed by ramming a tanker that explodes, causing other cars to explode as well. This is a mix of distance rendering followed by a detailed near-rendering action sequence, and the title thankfully spits out frame time data.
There are no presets for the graphics options on GTA, allowing the user to adjust options such as population density and distance scaling on sliders, but others such as texture/shadow/shader/water quality from Low to Very High. Other options include MSAA, soft shadows, post effects, shadow resolution and extended draw distance options. There is a handy option at the top which shows how much video memory the options are expected to consume, with obvious repercussions if a user requests more video memory than is present on the card (although there’s no obvious indication if you have a low end GPU with lots of GPU memory, like an R7 240 4GB).
To that end, we run the benchmark at 1920x1080 using an average of Very High on the settings, and also at 4K using High on most of them. We take the average results of four runs, reporting frame rate averages, 99th percentiles, and our time under analysis.
All of our benchmark results can also be found in our benchmark engine, Bench.

The multiplier chart doesn't make sense.The single core is 5Ghz, but Intel is quoting 4.7 Ghz all core and you're showing 4.4 identical to 8700K. I understand the base frequencies are the same, but the default multiplier for the 8086K should be higher. Is this a possible bios glitch or is the multiplier chart in the CPU not correct?

Boost frequencies are all the same on 5 cores. there is a youtube video with somebody testing this chip on a z370 gaming 7 and you can clearly see in that video that boost is the same on all cores except 1. Intel = lame.Ian Cutress - Monday, June 11, 2018 - link
Where is Intel promoting 4.7 GHz all core?HStewart - Monday, June 11, 2018 - link
One thing that is strange is the name - the Original IBM PC that started this whole PC industry used the intel 8088 processor and not the Intel 8086 processor. The difference is that 8088 has 8 bit external and 8086 has 16 bit external - But CPU's used 16 bit internally. No internal Floating processor until the 386 line.But it wild that it been 40 years - I have an original IBM PC - in my downstairs closet, I remember while at Georgia Tech - putting a 2Meg Ram card into and booting up to 1.4Meg ramdisk and loading Microsoft C 3.0 compiler on it.
As for new one - it would be cool if they actually included the original chip also as part of collectors edition.

8088 shipped in 79, was a variant of the 8086. 8086 was the first to 1M transistorspeevee - Monday, June 11, 2018 - link
"No internal Floating processor until the 386 line."486. 386 still used 387 AFAIR. There were even 487, but it was just renamed 486 to be installed with 486SX.

Yes I forgot that - the 486 was the one with Math Coprocessor.AsParallel - Monday, June 11, 2018 - link
Addition. The 8087 was the floating point coprocessor for the 8086/8829a - Monday, June 11, 2018 - link
You didn't put 2mb of RAM in an original IBM PC it supported 256kb max.HStewart - Monday, June 11, 2018 - link
I had a special card in the PC - it was EMS memory - that could also fill up the main system memory to 640kb - instead of normal cache mode use by the card - I configured it as ram drive. Memory above 640Kb was directly accessible by the system.
