A Broadwell Retrospective Review in 2020: Is eDRAM Still Worth It?
by Dr. Ian Cutress on November 2, 2020 11:00 AM ESTGaming Tests: World of Tanks
Albeit different to most of the other commonly played MMO or massively multiplayer online games, World of Tanks is set in the mid-20th century and allows players to take control of a range of military based armored vehicles. World of Tanks (WoT) is developed and published by Wargaming who are based in Belarus, with the game’s soundtrack being primarily composed by Belarusian composer Sergey Khmelevsky. The game offers multiple entry points including a free-to-play element as well as allowing players to pay a fee to open up more features. One of the most interesting things about this tank based MMO is that it achieved eSports status when it debuted at the World Cyber Games back in 2012.
World of Tanks enCore is a demo application for its new graphics engine penned by the Wargaming development team. Over time the new core engine has been implemented into the full game upgrading the games visuals with key elements such as improved water, flora, shadows, lighting as well as other objects such as buildings. The World of Tanks enCore demo app not only offers up insight into the impending game engine changes, but allows users to check system performance to see if the new engine runs optimally on their system. There is technically a Ray Tracing version of the enCore benchmark now available, however because it can’t be deployed standalone without the installer, we decided against using it. If that gets fixed, then we can look into it.
The benchmark tool comes with a number of presets:
- 768p Minimum, 1080p Standard, 1080p Max, 4K Max (not a preset)
The odd one out is the 4K Max preset, because the benchmark doesn’t automatically have a 4K option – to get this we edit the acceptable resolutions ini file, and then we can select 4K. The benchmark outputs its own results file, with frame times, making it very easy to parse the data needed for average and percentiles.

WoT always appears to be a good test of CPU gaming, however only in the lowest resolutions are the Broadwell parts competitive. As we crank up the settings, the minimum frame rates are more indicative of Broadwell positioning.
For our Integrated Tests, we run the first settings.
All of our benchmark results can also be found in our benchmark engine, Bench.

great reviewsadly i7-5775C's are still selling for $100+ on ebay. Not quite worth the upgrade over the i7-4790K, with graphics cards continuing to be by far the largest factor.
But to me it also shows there is no need to jump into the latest and greatest cpu, because these old cpus are still keeping up just fine.

> sadly i7-5775C's are still selling for $100+ on ebayohhhh, that makes me curious as to how they compare to 3100/3300X chips now

So the conclusion is Optane could play a big role in future?Leeea - Monday, November 2, 2020 - link
no.Optane is slower then normal RAM.
Optane is a faster more limited version of an SSD. Specifically it has RAM like read performance in some areas, while having SSD like write performance in other areas.

SSDs are much slower than Optane in writes.The worst case performance for Optane is better than the best performance for an SSD in writes.

"The worst case performance for Optane is better than the best performance for an SSD in writes."may haps Optane will optimize when used with code compiled to use only memory-to-memory execution and no hard I/O?

I would have loved to see Intel embed a couple of gig of Optane on every mobo or in every CPU - at scale it would have been cheap - and we would get the benefits of instant app start, damn fast reboot etc. That would make a bigger difference to the end user experience than 15% on benchmarks. But no, it came out with poorly implemented tiering software, via expensive almost unused add-in cards. Optane had so much mass-market potential, sadly I think it’s screwed now for use outside the datacentre. Intel of all people should know how tiered storage works, why did they screw it up so badly? They even had a shining example in Apple’s Fusion drive to follow (copy) but still messed it up.Jorgp2 - Monday, November 2, 2020 - link
Have you considered asking supermicro for a skylake GT4e review sample?f00f - Monday, November 2, 2020 - link
That's intel's vision of "embedded" DRAM which is only a kind of embedded, because it is on a separate die. If you look for a proper implementation, look at POWER7 processor (2010) with L3 as eDRAM on the same die as cores.jospoortvliet - Wednesday, November 4, 2020 - link
I am a bit surprised amd didn't embed 32 or 64mb memory in the i/o chip... that would probably be relatively easy and affordable.
