Intel just launched its new Core i9 range of processors, but Coffee Lake news continues to roll out, as Coffee Lake is a refresh/optimized slice of Kaby Lake that supports more than 4 CPU cores.
A new engineering sample has turned up on the SiSoft Sandra benchmark database, showing that Intel will have 6C/12T CPUs at 3.5GHz, and over 4.2GHz with Turbo enabled. We should expect 256KB of L2 cache per core, and 9MB of shared L3 cache. There's also a variant of Coffee Lake that will include a larger 12MB of L3 cache, too.
We should expect the Coffee Lake-S series to come in 4C/8T with GT2 graphics, as well as 6C/12T with GT2 graphics. There will be Coffee Lake-S and Coffee Lake-H series processors, but we might see Intel change the socket from LGA 1151 to something else with Coffee Lake, but let's hope they don't - alright?
The NDA has lifted on AMD's next-gen Epyc CPU range of processors, with the company detailing some of the pricing on its Xeon CPU competitors - with some hefty pricing at the flagship end of the scale.
AMD will have a bunch of 32C/64T options, with the Epyc 7601 flagship CPU that is available right now for $4200. Under that, we have the Epyc 7551 without pricing yet, but the Epyc 7501 is priced at $3400 and also available today. Towards the end of July, there will be the Epyc 7401 for $1850, the Epyc 7301 for $825, Epyc 7281 for $650, and Epyc 7251 for $475.
Our resident CPU editor Steven Bassiri, has detailed AMD's new Epyc CPUs here - with a more detailed piece on the way very soon.
Intel is on the verge of releasing its new X299 platform, with its new Core i7-7740K processor that seems to be hitting 5GHz pretty easily, and at low voltages - so low temps, too.
VideoCardz has got the reviewers' guide on its hands, and based across 100 samples of the Core i7-7740K, it should hit 5GHz with just 1.205V of power. At its worst, the 7740K needs 1.341V to hit 5GHz. The guide says that the Core i7-7740K has a higher overclocking ceiling than the 7700K, with 5.1GHz achievable with 1.255-1.411V.
The massive multi-threaded consumer CPU war is now starting thanks to AMD hitting Intel where it hurts with Ryzen and hitting 8C/16T @ $499... but Ryzen ThreadRipper with up to 16C/32T is on the way, so the preemptive strike from Intel with Core i9 happened.
Now we're seeing the first review of Intel's upcoming Core i9-7900X, their new X299-based Core-X series processor with 10C/20T of CPU performance that seems to perform well, overclock well, but is priced pretty high. Hexus has published their review from an Intel CPU sample that was not provided to them by Intel - so they could throw the review online and not worry about Intel's legal team emailing them saying they've broken NDA.
We can see that the fresh X299 chipset needs some more time to mature, but we have some gaming and overclocking charts for you to gander over - and consider buying the 10C/20T chip in the form of the Core i9-7900X over the upcoming Ryzen ThreadRipper range from AMD. My tip: wait.
AMD is killing it with their new Zen CPU cores, with Ryzen already a success and Ryzen ThreadRipper going for Intel's throat - but what about the server market? This is where Epyc comes into play, with the upcoming Epyc 7000 series from AMD. VideoCardz picked up the news, with some details on the Epyc 7000 series:
- up to 32 High-Performance "Zen" Cores
- 8 DDR4 Channels per CPU
- Up to 2TB Memory per CPU
- 128 PCIe Lanes
- Dedicated Security Subsystem
- Integrated Chipset
- Socket-Compatible with Next Gen EPYC Processors
No compromise 1-Socket
- Right-size underutilized servers
- Optimize storage and heterogeneous compute
- Low power consumption
- Up to 20% lower cap-ex
AMD Epyc 7000 Series: EPIC PERFORMANCE
There's some huge performance increases over Intel's Xeon E5-2699A v4 processor, which is a 22C/44T @ 3.6GHz CPU, with 55MB of cache, and a price of $4000+. We have 47% more performance over the single socket CPU, but given there are 18 more CPU threads (albeit at 400MHz slower clocks), AMD is going to send some massive shocks throughout the server market with Epyc.
Remember the fully integrated voltage regulator ( FIVR) introduced with Haswell CPUs? Turns out that news of Intel axing the technology was not completely true. Intel's previous FIVR was implemented to reduce motherboard voltage regulator (VR, VRM, or MBVR) complexity, as it fed the CPU a single voltage and the CPU then internally branched off, reduced, and controlled the other voltages needed for other CPU domains (graphics, system agent, cache, IO, etc.).
Traditionally, CPU voltage regulators are fed 12v from your main system power supply, and then they reduce it down to voltages below 2v for the CPU and its different domains. However, as CPUs became more complex they required multiple separate VRs, each with their own controllers (PWM Controller). Adding more external VRs not only increases motherboard costs because of the need for each VR to be individually controlled, but also more importantly, it takes up motherboard real estate which is scarce on a motherboard with eight memory DIMMs surrounding the CPU. Over the past week, Intel quietly made public volume 1 of the Skylake-X datasheet, and you can find it here: Intel Skylake-X Datasheet Volume 1 of 2.
In table 1-1 on page 14 we find that "IVR" will be referenced in the datasheet, and it stands for "Integrated Voltage Regulation (IVR): The processor supports several integrated voltage regulators." Later in the datasheet we find reference to the fact that the IVR is related to the previous FIVR through a signal name called "FIVR_Fault", which "Indicates an internal error has occurred with the integrated voltage regulator. The FIVR_FAULT signal can be sampled any time after 1.5 ms..." We then learn further down about the VCCIN signal, "1.8 V - 1.55 V input to the Integrated Voltage Regulator (IVR) for the processor cores, lowest level caches (LLC), ring interface, PLL, IO, and home agent. It is provided by a VR 13.0 compliant motherboard voltage regulator (MBVR) for each CPU socket.
AMD really has the high-end desktop market in a twist with their upcoming Ryzen ThreadRipper CPUs, with a new tease of the Ryzen ThreadRipper 1950X processor, a 16C/32T part with a purported 3.4GHz base clock.
The latest news is comign from a purported engineering sample on the ThreadRipper 1950X processor, which packs a base CPU clock of 3.4GHz and XFR boost clock of up to 3.7/3.8GHz. We should expect a huge 32MB of L3 cache, 8MB of L2 cache, bringing us to a total of 40MB of cache. In some benchmarks, it has been compared to Intel's higher-end Xeon E5-2697A V4 processor that features 16C/32T @ 2.6GHz base and 3.6GHz boost.
The multi-core score of the Xeon processor is 30,450 while the ThreadRipper 1950X hits 24,539... but I'm sure there are plenty of optimizations that AMD will be making just like the normal Ryzen CPUs, and then the motherboard makers will surely optimizations for ThreadRipper and its multi-core performance.
Intel's new Core i9 range is getting flashed around, with the upcoming 10C/20T part hitting 5GHz with an AIO liquid cooler. Intel's upcoming Core i9-7900X has reached 5GHz with the AIO liquid cooler, and even 4.5GHz on air, all on 1.15V - and with all CPU cores enabled.
The new Core i9-7900X will arrive with 10C/20T of CPU power, 13.75MB L3 cache, and 3.3/4.3GHz for base/boost, respectively. But Intel's new Turbo Boost 3.0 technology will overclock the 10C/20T chip to 4.5GHz, which is a huge upgrade over the current high core count CPUs like the Core i7-6950X. Intel's upcoming Core i9-7900X will have a TDP of 140W, and its X299 chipset will feature 44 PCIe 3.0 lanes.
Intel will be pricing the new 10C/20T Core i9-7900X at $999, and considering the Core i7-6950X debuted at $1500 and is still $1500 on Amazon right now - all with the same 10C/20T, but at much lower clocks (3.0/3.5GHz for base/boost), it's a steal. AMD will be competing big time with their upcoming Ryzen ThreadRipper CPUs offering up to 16C/32T, but their spiffy new X399 chipset rocks 64 PCIe 3.0 lanes, beating Intel out by a fair chunk.
Intel is reportedly launching its new Core i9 range of processors next month, starting with the Core i9-7920X (12C/24T) but the 14C/28T, 16C/32T, and 18C/36T processors will be launching in October.
The first phase of Intel's new Core launch will see the 4/6/8/10-core models launch, while the second phase will see the 12C/24T chip launch, and then finally the mudslide of 14/16/18-core parts. Intel will reportedly begin accepting pre-orders of the new 4/6/8/10-core Kaby Lake-X and Skylake-X processors on June 19, shipping to consumers on June 26. All of these processors will work on the new X299 chipset.
Intel's upcoming 12C/24T processor in the Core i9-7920X will launch in August for a hefty $1199, while the super high-end Core i9-7980XE with 18C/36T of power will launch in October.
Intel has just made its upcoming Cannon Lake CPU architecture official, with its 9th-gen Core processor on track and made on the 10nm process.
Intel also took the time to announce that its second micro-architecture built on 10nm is taped out, with details on Ice Lake to follow. Intel is reacting in a scared fashion as I said months and months ago now, throwing out its 18C/36T processor at Computex 2017 without any details, a gimped X299 chipset compared to the ThreadRipper ready X399 chipset from AMD which has 64 PCIe 3.0 lanes compared to just 44 PCIe 3.0 lanes on X299.
The new Cannon Lake CPUs will be a die shrink of the Coffee Lake chips, so don't expect huge things from it, apart from lowered TDP and possibly higher clocks. Ice Lake will be the bigger one, something like the upgrade from Broadwell to Skylake, and is expected in 2H 2018.
