7-Zip
7-Zip is an open source Windows utility for manipulating archives. We measure the Total Rating performance using the built-in benchmark tool. The test stresses all CPU cores to 100% and shows an affinity for memory bandwidth.
Mozilla Kraken
Mozilla Kraken is a browser-based JavaScript benchmark that tests a variety of real-world use cases. We use Chrome as the test browser. The test exhibits very little multi-threading and shows an affinity for CPU clock speed and IPC.
Sandra Memory Bandwidth
Overview:
The multi-threaded 7-Zip test continues to show the i9-7900X as a performance powerhouse. Performance increases over a 6950X are 14% at stock and 9% when overclocked. Compared to Ryzen 7 1800X, the 7900X is 42% quicker at stock and 50% better when both chips are overclocked. If you have workloads which demand a sizeable amount of file archival, the i9-7900X is a smart choice.
Mozilla Kraken is displaying surprising results given its preference for IPC and clock speed more than cores. The 7900X puts in a good showing thanks to its Skylake architecture and fast lightly-threaded boost clocks of 4.3GHz or 4.5GHz.
Memory bandwidth is past 50GBps for the quad-channel DDR4 solutions and Skylake-X is no exception. There seems to be an early bug with this test as the bandwidth for our Core i9-7900X system with 3200MHz C14 G.SKILL DDR4 should be closer to the i7-6950X result of 60GBps. A BIOS or software update should fix this as we see no reason why memory bandwidth should be reduced compared to Broadwell-E. All-out memory bandwidth is an area where Intel's quad-channel HEDT platform has a clear advantage over dual-channel Ryzen competition.
Good review . Honestly even if Intel gets all the goodness of being a fast processor its highly priced. Also poor thermal performance is a big deal because processor eventually runs hot and performance will take a toll.
I am personally waiting for Threadripper AMD’s line up to compete with Intel’s half cooked CPU.If AMD TH has good price and good thermal efficiency then even if it is a bit slower then Intel’s offering people will go for it. Ryzen 7 and especially Ryzen 5 1600 cpu proved this already
What about VRM temperatures? 🙂
This is a review of the CPU. The VRM temps are going to vary depending on the board and its overly extravagant but largely useless cooling shroud.
Brilliant and thorough review, thank you very much.
I’d be happy with quad memory-channel i7-7740X with 44 PCI-e lanes. Fast enough for _everything_ I need, and would have enough memory and PCI-express bandwidth for the workloads I run (don’t need 10c/20t).
Unfortunately, it doesn’t exist. Either I have to buy the crippled i7-7740x with 28 PCIe and dual channel memory OR I have to buy the over-priced space heater that is the 7900X with a motherboard that fries eggs with the VRMs and sucks so much electricity out of the socket that I can hear the kill-o-watt whirr like crazy in the background while notes keep flying out of my wallet.
No thanks Intel. You really outdid yourself this time around.
I will wait for the ThreadRipper from AMD.
I like your test, but let me make a small correction, 7900X is faster then Ryzen only because of more cores and higher clock, not due to “modern architecture” (which while newer? then Ryzen is by no means better). But to count my chickens 🙂 Ryzen_OC is 4.05Ghz, 7900X_OC is 4.6Ghz
1776*1.25(because Intel has 25% more cores then AMD)=2220
now to equalize core speeds: 2220*4.6/4.05=2521 (the Ryzen score as it would be at 4.6Ghz) – IPC wise Intel (scored 2449) is still a bit worse then AMD in Cinebench.
I’m not saying that AMD is better since it can’t at the moment reach 4.6Ghz nor does it have 10 core CPU to fight with.
Similar thing happens with x265 encoding benchmark: 30,6*1,25*4,6/4,05=43,4444444 – a bit faster then Intel. And it is all in tasks that put use to AVX2 and there is still Intel advantage in 4 channel memory.
Well, at least you can wait a bit and see if Threadripper is actually better then Intel – there is no guarantee it is. Especially for lightly threaded tasks that you speak of (that per chance require high core clock that will most likely not be reachable on TR).
AMDs single core IPC is slightly worse than Intels, but AMDs implementation of SMT vs Intels HT brings it out on top by a slight margin at the same core/clocks in multi threaded benchmarks while losing in the single core benches. And then AMD doesn’t really OC well, neither does memory clock up well, its improving of course but not at any great pace.
Bottom line w/ Ryzen is mem clocks pf 2933 are a no brainer, and known to work 3200 components are common.
Thats the consensus on the street.
A pact with the devil will always bite u in the ass.
How can u trust intel?
Buy a $999 cpu w/ scads of lanes, & discover there is an charge to use nvmeS as they should be. Slimy.
The new keying system shows they use their research dollars to effect better ways of screwing customers. A good look guys.
I would buy amd gear if same money and 10% worse. My time, upgradeability, conscience and dignity are worth something too, thanks intel.
AMD probably are 10% worse in the criteria intel like to use, but AMDs modular/fabric architecture, is miles better than intel has or will have achitecture, for future cost effective ~equivalent outcomes.
BTW the prices u list for amd dont reflect reality. Both are much cheaper on amazon etc. Further, the widely regarded sweet spot is the 12 thread r5 1600, at ~$220
Lanes are just sufficient on ryzen, for a 16 lane gpu, a 4 lane nvme ssd onboard and a 4 lane pcie2 nvme ssd (~1.6GBps, or triple a sata ssd).. Beyond that, u have stacks of sata and .5GBps pcie2 expandability, but no 1GBps pcie3 lanes
note also, amd pcie3 lanes are direct to the cpu, not via switches and bridges like most intels.
Newsflash, the i7-7740X only has 16 PCIe Lanes, not 28!
Test w/ agesa 1006 please…..
Not sure why you would complain about a crippled quad core and decide to wait for a 10 core minimum threadripper lol. Amd has some amazing stuff coming out, but it will not have the IPC of intel.
The 8 core intel is actually a pretty sweet chip. It can overclock 2 of its best cores to 4.5 ghz for single or two thread tasks and 4.3 turbo on all cores. The thermal is only an issue when overclocking and when you get this many cores it will always be a problem when overclocking. Amd hasnt been able to go over 4.1 ghz yet.
Intel PCIE lanes are direct to the cpu as well. And if intel says a cpu has 16 lanes (like the 7700k) then those are dedicated to the GPU. The rest, in that case, come from the chipset via dmi 3. This is unlike AMD who is currently *overstating* PCIE lanes available for video. Sorry to burst your fanboy delusion bubble
I strongly suspect nothing you do requires 44 PCIE lanes or quad channel RAM. People complaining
about 7900x, and somehow not satisfied with *either* Kaby Lake *or* Ryzen 5/7, and obsessing instead over “Thread Ripper” sound generally clueless.
AMDs marketing is really working for TR. Somehow every hump on comment threads is now convinced they’re doing all sorts of things that somehow justify *32 threads*, even at lower IPC, and *dozens* of PCIE lanes and *mountains* of memory bandwidth. Enormously unlikely.
You can’t run a 32GB kit @3200Mhz on Threadripper cpu, it just fails to boot. Worst memory controller ever on a cpu i guess. It maxes out @ around 2800Mhz if you install 32gb of ram. If you go higher like 64gb, then you end up with 2133Mhz ddr4 speeds or 2400 if you are lucky.
Whereas I am running 64GB 3800Mhz CL15 kit with my 4.8Ghz 7900X. Unleashes my 2x overclocked Titan Xps in SLI. AMD doesn’t clock well, has the worst memory support and has lower IPC and thus lower gaming performance. It’s just good for rendering & encoding farms.
