It’s likely both of these leaks are accurate. In fact, Videocardz also leaked similar information just a few days ago, and the Baidu leak correlates very closely. Though this leak isn’t coming from the likes of Videocardz or Apisak, it does seem legitimate. Continue to the next page for thermals, delidding, & liquid metal.A user on the Chinese-based Baidu forums has leaked Cinebench R15 benchmarks (and some CPU Z info) of what is apparently a Ryzen 5 3600. Intel i7-8700K Cinebench Score (CORRECTED) The synthetic benchmarks have been mostly recalculated to reflect this issue of Gigabyte's BIOS. Fortunately, these do not impact our gaming results, as we used F4 and F5a for those (with MCE disabled by default). NOTE: We observed issues with Gigabyte's F2 EFI revision that forced some tests to run in MCE mode. Let’s get some quick synthetics out of the way, then move on to the real testing: Just overclock one to 4GHz and you've now represented all Ryzen 7 CPUs at 4GHz. The 1700 was used for comparison because it is the 1700X & 1800X. All tests were run BEFORE the delid (stock conditions) except for the liquid metal tests, obviously. To answer a few common questions this morning: We’ll detail the test method updates in a separate content piece in the future, as this content is presently being written while the writer is falling asleep for microseconds, hours ahead of embargo. Previous platform and test methodology information can be found in more recent CPU reviews, but we are updating in big ways for CL onward. An EVGA SuperNOVA T2 1600W PSU was used as the primary power supply, with a Kraken X62 (max pump + fan speeds) used for the cooler on all benches.
CINEBENCH 8700K DRIVERS
Part of this means updating drivers to version 385.69, with Windows now updated to Creator’s Update (game mode disabled) for new CPU benchmarks and reviews. We’ve also moved to a 1080 Ti FTW3 from the 1080 FTW1, making for a stark difference in GPU bottlenecking headroom between the legacy and new tests. A GeIL EVO X kit was used across the board, with some exceptions made for a GSkill RGB Trident Z kit that had been reconfigured to match the GeIL timings. Gigabyte's Ultra Gaming Z370 board seems to output lower voltage than we ask for in BIOS, which makes it difficult to gauge what's actually going on versus what you're telling the board to do.Īll of the new (non-legacy) CPU tests were conducted with 3200MHz CL16 memory.
Some of this comes down to the motherboard. We haven’t re-attempted overclocking with liquid metal yet, but did delid the CPU with Rockit Cool’s delid kit and used Conductonaut liquid metal. We struggled to hold 5.0GHz stable in some production tests (like Blender), and required high voltage to hold 4.9GHz. We ended up stuck at 4.9-5.0GHz with a Vcore of 1.40-1.42, a far cry from Der8auer’s golden sample unit at 5.2GHz and 1.375Vcore: It seems that we received one of the worst samples of the media lot, when it comes to i7-8700K overclocking. The new testing involves a new suite of games, new testing methods (including 1440p tests), delidding & LM testing (debuted in our X299 coverage), and new production render testing. The idea is to conduct both simultaneously, with the older option acting somewhat like an LTS build as it is gradually retired. These tests will be slowly phased-out as we accumulate more data for the new benchmarks. Coffee Lake marks a refresh of our CPU test suite, though we are still carrying-forward some now-retired tests for comparative/archival data. Our i5-8600K review will post separately, as this is dense enough as-is.Īs a foreword, we’ll be deprecating our old CPU benchmarks going forward. Ryzen, power draw, and production benchmarks. Our Intel i7-8700K review will focus on delidding, liquid metal application, overclocking, gaming & streaming benchmarks vs. Either way, the i7-8700K is here now, and we’ve got a densely packed review covering most aspects of Coffee Lake. Intel’s i7-8700K premiere CL CPU carries an MSRP target of $360 1ku, a $10-$20 jump over Kaby Lake 7700K CPUs with fewer cores and similar frequencies. One thing we won’t know, of course, is whether the pricing is some sort of a response to Ryzen. X299 moved forward to compete with Threadripper, and Coffee Lake received a similar treatment. Intel’s Coffee Lake CPUs aren’t a hard “response” to Ryzen the CPUs have been taped-out for a while now, but the response appears to align more with the release timeline and pricing.
