Intel's Just Launched 8th Gen 'Coffee Lake' Processors Bring the Heat To AMD's Ryzen

Posted by BeauHD on from the new-and-improved dept.

bigwophh writes: The upheaval of the high-end desktop processor segment continues today with the official release of Intel's latest Coffee Lake-based 8th Generation Core processors. The flagship in the new lineup is the Core i7-8700K. It is a 6C/12T beast, with a base clock of 3.7GHz, a boost clock of 4.7GHz, and 12MB of Intel Smart Cache. The Core i5-8400 features the same physical die, but has only 9MB of Smart Cache, no Hyper-Threading, and base and boost clocks of 2.8GHz and 4GHz, respectively. The entire line-up features more cores, support for faster memory speeds, and leverages a fresh platform that's been tweaked for more robust power delivery and, ultimately, more performance. The Core i7-8700K proved to be an excellent performer, besting every other processor in single-threaded workloads and competing favorably with 8C/16T Ryzen 7 processors. The affordably-priced 6-core Core i5-8400 even managed to pull ahead of the quad-core Core i7-7700K in some tests. Overall, performance is strong, especially for games, and the processors seem to be solid values in their segment.

      The piddly PCIe provisions are a shame though... no improvement (in lane count) whatsoever since they pulled the controllers onto the CPU die (LGA1156, Nehlaem). Note that the addition of each lane requires no less than two additional pins on the socket, so they'd have to re-purpose some pins to do it, and there aren't really a lot to spare. I know there were a fair number (20+) on the 1155 that weren't marked RSVD or anything else, but I'm having some difficult finding data on 1151. From the images I have found, it appears that practically every pin is connected to something, and fewer than 20 RSVD pins remain at all.

      Prove that the PCIe lanes are being maxed out for gaming, daily computing, video editing, etc. and then I'll care. Yes, PCIe lanes matter for specific applications but the vast majority of gaming and higher end enthusiast systems are not maxing out the existing PCIe 3.0 lanes and DMI 3.0 bandwidth.

      Current benchmarks show very little difference between SSD and NVMe in boot times and gaming performance. The main difference is transferring large files and loading large files into memory (i.e. video editing). NVMe M.2 drives are also somewhat expensive in comparison to SSD.

      I upgraded the NVMe M.2 drive on my Surface Pro 4 to a Samsung 960 Pro while fixing the cracked screen. I bought a PCIe NVMe adapter card to copy the OS from the original NVMe drive to the new one. Windows 10 had no problems accessing it with no third party drivers required. I'm pretty sure that NVMe support will be integrated into Intel motherboard designs through third party controllers.

      Basically, it's great that AMD CPUs have higher end features that Intel as it gives us choice and drives competition. But how useful those features are will depend on you use case.

      No problem.
      Intel have improved their cores and production the whole time and have had quad core desktop chips since Core 2. They launched six core Sandy-Bridge-E processors back in 2011 and have had Xeons with many cores too for a very long time.
      So it's been around. Intel just haven't put it into the main-stream market. The six-core i7 5820 from 2014 didn't really cost more than the i7 4790K though ($10-$20?) so even back then you could get a six-core CPU for the price of a quad-core one. The motherboards and RAM for the HEDT platform (DDR4 in this case) was more expensive though.

      With quad-core on core quad, core i, on Sandy-bridge (2xxx), Ivy-bridge (3xxx), Haswell (4xxx), Broadwell (5xxx), Skylake (6xxx), Kaby lake (7xxx) I've been waiting to get it hopefully I think even with Broadwell and over and over again it didn't happened even though they have shrunk the manufacturing process and the HEDT chips went from 6 to 8 to 10 cores and even more now (18?), it was bound to happen eventually and hopefully it would have happened now anyway. As in the lower end though whatever that would get this sort of upgrade or not and as for whatever the HEDT line would get as high core counts as they ended up getting that could be questioned. But something like the i7 8700K I've waited on and expect for a long time. It was obvious it would happen eventually.

      or the much more likely answer that they've been sitting on new features and performance because they wanted to milk the previous generation for all it was worth.

And now it's launched and for multi-threaded at stock it doesn't really live up to over-clocked 1700 or stock 1800X performance at all tasks but with both OC it likely is very close on both. At single-core performance it's better of course. Still for streaming it seem like Ryzen 7 may still have a small advantage.

      Our measures clearly show that, on Nehalem,
      on most benchmarks, 12 to 16 MPKI are encountered, that is about 240 to 320 cycles are lost every 1 kiloinstructions. On the next processor generation Sandy Bridge, the misprediction rate is much lower: generally about 4 to 8 MPKI on Javascript applications for instance, i.e. decreasing the global penalty to 80 to 160 cycles every Kiloinstructions. On the most recent processor generation Haswell, the misprediction rate further drops to 0.5 to 2 MPKI in most cases, that is a loss of 10 to 40 cycles every kiloinstructions.

      That's an order of magnitude difference. In their their Python benchmark the Nehalem has an average of ~1.5 instructions per clock (IPC) while Haswell has an average of ~2.4 IPC, a 50% increase over Nehalem. The branch predictor is likely a big factor in this.

Depending on your hardware, you may be capable of disabling the management engine on Intel's via some external hardware reprogramming device, and there's some flag that isn't available to the consumer but is available to system integrators which can result in the ME not being loaded (and some, like Purism, are chasing this down).
