Rise of the Tomb Raider
One of the newest games in the gaming benchmark suite is Rise of the Tomb Raider (RoTR), developed by Crystal Dynamics, and the sequel to the popular Tomb Raider which was loved for its automated benchmark mode. But don’t let that fool you: the benchmark mode in RoTR is very much different this time around.
Visually, the previous Tomb Raider pushed realism to the limits with features such as TressFX, and the new RoTR goes one stage further when it comes to graphics fidelity. This leads to an interesting set of requirements in hardware: some sections of the game are typically GPU limited, whereas others with a lot of long-range physics can be CPU limited, depending on how the driver can translate the DirectX 12 workload.
Where the old game had one benchmark scene, the new game has three different scenes with different requirements: Geothermal Valley (1-Valley), Prophet’s Tomb (2-Prophet) and Spine of the Mountain (3-Mountain) - and we test all three. These are three scenes designed to be taken from the game, but it has been noted that scenes like 2-Prophet shown in the benchmark can be the most CPU limited elements of that entire level, and the scene shown is only a small portion of that level. Because of this, we report the results for each scene on each graphics card separately.
Graphics options for RoTR are similar to other games in this type, offering some presets or allowing the user to configure texture quality, anisotropic filter levels, shadow quality, soft shadows, occlusion, depth of field, tessellation, reflections, foliage, bloom, and features like PureHair which updates on TressFX in the previous game.
Again, we test at 1920x1080 and 4K using our native 4K displays. At 1080p we run the High preset, while at 4K we use the Medium preset which still takes a sizable hit in frame rate.
It is worth noting that RoTR is a little different to our other benchmarks in that it keeps its graphics settings in the registry rather than a standard ini file, and unlike the previous TR game the benchmark cannot be called from the command-line. Nonetheless we scripted around these issues to automate the benchmark four times and parse the results. From the frame time data, we report the 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.
