Intel Rolls Out Kaby Lake Desktop CPUs, Linux Results Later

[maletor]

So does the Kaby Lake support HDMI 2.0 via the HD 630 on top of their open source drivers?

[Johners]

Kaby Lake parts should perform better than their equivalent Skylake part due to the faster clock speeds of the components. These newer chips also overclock a lot better with around 75-80% of Kaby Lake i7 CPUs being easily overclockable to 5 GHz. Another benefit of these newer chips, for desktop and mobile chips, is the on-die silicon for decoding 4K video. This is why Netflix on the PC requires a Kaby Lake processor for 4K playback (it also requires Windows 10 and Edge but that is for the software side of things).

Also Michael, you might have a better chance of getting these CPUs and GPUs if the reviews had Windows and Linux benchmarks as well as Real World and Canned benchmarks. They'd bring more traffic to Phoronix and they'd also provide a more valid set of data by being able to draw comparisons between generations of hardware and the same hardware on different platforms.

Any evidence that Ryzen is "much much" more powerful than an older Intel part? Where has AMD posted the official price list for these Ryzen parts either? Or are you just blindly believing anything that AMD marketing tells you months in advance of a real chip actually launching. You know, just like you did when Bulldozer "launched".

AMD certainly weren't showing us a variety of benchmarks showing real IPC and power consumption improvements before releasing Bulldozer. Furthermore the microarchitecture is far more advanced than anything we've ever seen from AMD. Ryzen is twice as wide, has SMT, a micro-op cache, much lower latency cache system, and is much more power efficient. They were aiming for 40% IPC gains, but from my calculations, they are most likely around 53%. That puts them right in line with Kaby Lake floating point IPC-wise. While they were close to Intel in Blender, that Handbrake benchmark showed integer performance to far exceed Intel's. Looking at around 10%. If this is representative of integer performance on Ryzen this could be another Athlon 64 situation albeit not quite as dire for Intel.

supposedly unlocked AVX1/2 frequencies in kaby lake should be quite interesting to see compared to skylake AVX1/2 performance

what do you mean by avx frecuency?

There are benchmarks against Intel Extreme 8 cores. Prices are not officials, but speculations are around 500$ for the tier 1.

Ars Technica is not impressed:

For yet another year, high-end desktop CPU performance remains at a
standstill. With low-power laptops and all-in-ones continuing to
outsell desktops—and with high-end workloads like video editing, 3D
animation, and machine learning increasingly being offloaded to
GPUs—perhaps it was inevitable that Intel would stop caring so much
about its high-end consumer CPUs. Or maybe Intel's struggles with
the 14nm process forced its hand, and the last few years of
disappointing performance improvements are down to physics rather
than passivity.

what do you mean by avx frecuency?

There is new feature or BIOS option called AVX Offset to tune for overclockers it is, as AVX instructions are known to be power hungry and also known to hurt stability when overclocked. Basically with that feature user can do somewhat more main overclock, while reducing AVX frequency to keep overclock stable or say... keep main as it is but instead increase just AVX if you run software which rely on it, etc...

But any OC is always really sort of paperware, maybe you can do it maybe you will not, as beside knowledge about it user also need good sample and luck as always no guarantees there

Bulldozer was a tweak. Zen is a clean slate. Initial leaked benchmarks show Ryzen as performance competitive with the very top of the i7 range. Those who've followed Zen's development recognize the significance of Jim Keller's involvement. Market forces dictate a competitive price. Do the math, read between the lines, etc.

For several years now intel has essentially had a monopoly. If nothing else, the release of Ryzen will bring down the price of the intel parts. It's a win-win for consumers, why your tone is so negative?

Speaking of Bulldozer, Kaby Lake is intel's Bulldozer. Sales hype and a new model number, but almost zero improvement over Sky Lake.

I am cautiously optimistic that AMD can get back into being really competitive. It is going to be an interesting couple of years with the zen arch, HSA and all the things they have been building.
