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. 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 8700K did not seem to play nicely with RoTR. We'll go back and check this.

Awesome revies! Let's read...prisonerX - Thursday, October 5, 2017 - link
No need, here is a quick summary: "Intel blind panic."StevoLincolnite - Thursday, October 5, 2017 - link
At-least they have finally soundly beat my 3930K in the mainstream after 6 years.Still. No point me upgrading just yet.

Even then there's an interesting option if you want threaded performance; I just upgraded to a XEON E5-2680 v2 (IB-EP) for 165 UKP. Lower 1T speed for sure, but MT should be the same or better as a 3930K @ 4.8. No oc means more stable, less heat/noise/power, and being IB-based means it ups the slots to PCIe 3.0. Not a relevant choice for gaming, but a possibility for those doing VMs, rendering, etc., and just want to get by for a little while longer.Breit - Friday, October 6, 2017 - link
OR search for an XEON E5-1680v2... :)It's an Ivy Bridge-E 8c/16t chip that will fit in Sandy Bridge-E mainboards (x79) and has an unlocked multiplier opposed to this E5-2680v2. So with this you won't lose your overclocking ability.
But in the end, I guess that the greatly reduced power draw and the more "modern" platform from an i7-8700K system compared to the x79 platform will give it the edge here.

Very interesting that the 1680 v2 is unlocked, I didn't know that.Alas though, availability of the 1680 v2 is basically zero, whereas the 2680 v2 is very easy to find, and the cost of 1680 v2s which are available (outside the UK) is extremely high (typical BIN of 600 UKP, normal auction start price of 350 UKP, completed listings only shown for BIN items which were purchased for between 500 and 600 UKP). By contrast, I bought several 2680 v2s for 165 UKP each. Testing on a P9X79 WS (all-core turbo of 3.1) gives a very impressive 15.44 for CB 11.5, and 1381 for CB R15 which is faster than a stock 8700K (for reference, the 1680 v2 scores 1230 for CB R15). Note the following page on AT has a very handy summary of all the turbo bin levels:
https://www.anandtech.com/show/7852/intel-xeon-e52...
So, I'm very pleased with the 2680 v2 purchase, it's faster than my 3930K @ 4.8, runs with very low temps, much lower power draw, hence less heat, less fan noise and since it's not oc'd it'll be solidly reliable (this particular test system will eventually be in an office in India, so power/heat/reliability is critical). For the target systems in question, it's a great solution. Only thing I noticed so far is it didn't like me trying to set a 2133 RAM speed, but it worked ok at 1866; I can probably tighten the timings instead, currently just at 9/11/10/28/2T (GSkill 32GB kit, 8x4GB).
The 4930K I have though will go into my gaming system (R4E), since I don't mind the oc'ing fun, higher noise, etc., but it's not a system I'll use for converting video, for that I have a 6850K.
Ian.

Full throttle: yes. Panic: no. Blind: no.Zingam - Saturday, October 7, 2017 - link
Can you buy it? No? Paper launch of Unobtanium 8000? -> panic, PR propaganda bullshit and dirty Intel marketing tactics as usual targeted at lamer fanboys.This comment is written by an Intel user! ;)

We've got enough dumb Intel apologists here already, thanks.coolhardware - Sunday, October 8, 2017 - link
The i7-8700 is *finally* going to replace my trusty i5-2500K.Ordered my 8700 on Amazon http://amzn.to/2y9IamG ($319) and looking forward to a nice upgrade :-) That is a lot of CPU for the money IMHO.
Kudos to AMD for bringing competition back to the CPU market!
