Maybe that's the reason for the staggered releases, the oddly separated dates may mean new steppings and any actual bins currently would exacerbate the current problems.

memory latency is the important thing, and there's progressively less of it with higher speeds of RAM since CL isn't fully proportional to clocks.

The scuttlebutt of low bandwidth RAM is that it's much harder to find low latency 2400 than it is to find average latency 3200

this was a few days ago, but this is the important part http://semiaccurate.com/2017/02/22/amds-ryzen-7-1800x-beats-intels-i7-6900k-half-price/ quote:Charlie Demerjian the wccftech article is fairly sensational but I would not be surprised about intel being petty about AMD merely catching up to their last-full-gen poo poo

Can they just fire AMD's marketing and press relations department like 10 years ago, holy poo poo this is an embarrassing fractal of stupidity. Errata wasn't such a big loving deal a decade ago for Core 2 and POWER8 took a giant poo poo for a few weeks upon its unveiling but finally got things working right after a couple months.

Don Lapre posted:b b b but i thought it was gonna make intel have to basically give the 7700k away because it was going to be such a gaming monster  SMT not working properly at all is a surprise  production chipsets may be behind and BIOS with working SMT awaiting validation if this is theoretically a fixable thing, otherwise we're going to have early A64/Conroe errata comedy for days if not weeks.

Twerk from Home posted:It's fine, and "barely keep up with Haswell" is a decent result given that Broadwell was a teeny tiny improvement over Haswell. The truth is somewhere in the middle, it's better at some things and worse at others than Intel's chips. It's competitively priced for things that want 6+ slower cores and a decent product overall.  that wants fewer incredibly fast threads.Also, why the unholy gently caress is SMT broken on release?

Alereon posted:So to clarify, you're trying to use software to compress the video for the game you're playing in real-time? Yeah that'll be hard on a quad-core CPU but it seems like there's better solutions, like hardware encoding. Also, QuickSync duplicates your display when you encode with that, which is nice if you're playing at 1080p60fps, not so much when you're playing anything with a higher refresh rate or resolution

Intel cores have always been arranged as 1/H1/2/H2/3/H3.... and so on in Windows, as Ryzen is. I'm pretty sure that's just baseless theorycrafting when the real problem is that SMT just doesn't work properly in the first place. In unix-based systems, intel cores are arranged as 1/2/3/4/H1/H2/H3/H4. I can see how the problems arise if Ryzen doesn't follow this convention.

This isn't as bad as Phenom I because Ryzen is actually a functional chip The errata as of current are just slightly worse than the level of Conroe's teething pains, ie why Intel now has chipsets on lockdown

FaustianQ posted:My impression is that Ryzen can completely trounce Intel in performance per watt in mobile and server FaustianQ posted:Isn't there a disadvantage to doing this though? On the chip design, Intel has separated cache banks that are transparently unified by the time whatever reaches the OS. There's no reason why AMD couldn't do this, at least for Z+.

Ragingsheep posted:What's the difference between a mobile and desktop process? The mobile can't take as much power? Pascal (16nm TSMC) = Lower density design, better for achieving insane clocks and heat dissipation, low chip density and higher power consumption Sky/Kaby/Coffee Lake (14nm Intel) = Tries to be somewhere in between the above two Intel could actually make the high speed Lake CPU designs denser if they wanted to, but they want to sell 4Ghz Xeons someday and they have to have 3.2ghz-for-one-second "4.5w" processors as a bullet point for sales.

PC LOAD LETTER posted:You're right it doesn't. The DRAM speed does so setting a CL 17 stick to CL 15 won't do anything to the IF clocks but setting a stick of 2133 or 2400 DDR4 to 2933 or 3200 will effect the IF clocks and apparently can reduce inter L3 caches latency significantly while also boosting inter L3 cache bandwidth but I believe its currently unknown if bandwidth is a big factor there. Going by the Pcper article on the subject recently it really seems like inter L3 cache latency is the issue.

Their DRAM and NAND businesses are likely to be sold off to its competitors. Combined with the usual demand outstripping supply, you can expect it to get even worse in the fall.
