Sandra Processor Arithmetic
Sandra Cryptographic
Sandra Memory Bandwidth
The synthetic tests conducted by SiSoft Sandra give an indication of where each processor should fall in an ideal test scenario.
Performance in the Processor Arithmetic test is interesting as the overclocked i7-7700K manages to overcome its core count disadvantage and outperform a stock-clocked 6800K. Other than that, performance is still generally how we would expect it to be – Kaby Lake is faster than Skylake by virtue of its higher clock speeds.
The Cryptographic benchmark shows tendencies for liking architecture performance, clock speed, and also core count. Kaby Lake chips perform better than their core count would suggest (against BDW-E and DC) by virtue of the well-designed Skylake microarchitecture and high clock speeds.
Memory bandwidth is essentially a proxy for showing the performance of memory modules. With that said, the HEDT BDW-E chip's ability to use quad-channel DDR4 nets it the performance lead. Higher-speed DIMMs than the 2666MHz modules that we used would easily break the 50GBps bandwidth barrier. Kaby Lake hits 33GBps of memory bandwidth when using a pair of 3200MHz G.Skill DIMMs. Devil's Canyon is left lagging behind due to the use of dual-channel 2400MHz DDR3 memory.
Rushed out as an answer to Zen/Ryzen. You’re stupid if you buy one of these now without seeing what AMD will offer.
No, kaby lake was announced that will be little boost from skylake, the best of intel is coming from Cannonlake
It’s barely a “little boost”. Clock for clock, benchmark results show literally 0 improvement. Only improvement is slightly better OC.
Very disappointing performance it’s almost the same with 6700k why intel bothered to release this ??
Cannonlake looks more promising
Most pointless intel release to date. The day they go back to dropping the igpu on the i5/i7 range and keep them for the i3 will be the day we actually get improvements. I would expect if they dropped a CPU with a 5.0GHz out the box speed and some decent gains whilst loosing the intergration then almost all gamers running dedicated GPU’s would take note and buy.
As it is there is zero reason to look at this and wait to see what Ryzen (release January 2017) and Cannon Lake (Late 2017) do really if you have anything in the i5/i7 4 series or above.
It may well be that Cannonlake is the answer to Ryzen, however the release of the 7700k is inline with the Ryzen release and Cannonlake will be 9-11 months later.
The though that there will be people out there who’ll upgrade from Skylake to this…..
under performing junk I will pass
Not from Cannonlake. From Ice Lake in 2019. Intel is in a bad situation right now. They have no real developments in the works until 2019. Kaby Lake up to Coffee Lake are simple increments. Kaby Lake is just a Skylake refresh with a different name, and Coffee Lake will just be Cannonlake with six cores coming to the mainstream platform; essentially, the low-tier of Cannonlake-E rebadged. Like Broadwell-E’s 6800K/6850K.
I was hoping for better I was going to finally jump from my 2600k to this gen but there is very little difference between my cpu and 6700k and it looks like there is no difference between that and this new gen.
Hey y’all, i’ve read thru your comments about the Kaby Lake 7700k and I have a request. I am FINALLY able to afford to upgrade my “gaming rig” which is an old ThinkCenter Pent Dual Core E5500 with an Nvidia GeForce GT 730, so anything will be mo betta… My question is what to buy as the heart of a new Gaming Rig? I am Network Spt specialist so I can assemble myself but im not up to date on the best gaming gear. If you could please make recommendations? I can probably spend up to $1800 that I received from my late mother’s estate. Thanks, plz dont hate, i really need your input. Peace!
Best to wait for Zen, then you can get an i7 or the equivalent AMD CPU depending on which performs better or is better value for money.
Im on the same boat buddy, tired of this deliberate turtle play from both AMD and Intel.
Thank you, since you replied I’ve watched the Zen video at https://www.youtube.com/watch?v=4DEfj2MRLtA and I am definitely going to wait for the Ryzen release. In the mean time I will research the AM4 Mobos available and try to choose one. I have long been an avid Nvidia fanatic and never once thought about using a Radeon card but I must admit I find the new AMD Vega interesting. I am looking forward to seeing the benchmarks on it and possibly purchase one for my new gaming rig.
i returned my skylake for this, it was just a few dollar more considering the return cost. I think if i wasnt in the return window though there’s no chance id spend money on upgrading.
I needed(Old one died) a new CPU that’s the only reason I got kaby lake
I like the z270’s though
