AMD Ryzen 7000 "Zen 4" Processors Have DDR5 Memory Overclocking Design-Focus
AMD's first desktop processor with DDR5 memory support, the Ryzen 7000 series "Raphael," based on the "Zen 4" microarchitecture, will come with a design focus on DDR5 memory overclocking capabilities, with the company claiming that the processors will be capable of handling DDR5 memory clock speeds "you maybe thought couldn't be possible," according to Joseph Tao who is a Memory Enabling Manager at AMD.
Tao stated: "Our first DDR5 platform for gaming is our Raphael platform and one of the awesome things about Raphael is that we are really gonna try to make a big splash with overclocking and I'll just kinda leave it there but speeds that you maybe thought couldn't be possible, may be possible with this overclocking spec." We are hearing reports of AMD innovating a new overclocking standard for DDR5 memory, which it calls RAMP (Ryzen Accelerated Memory Profile), which it is positioning as a competing standard to Intel's XMP 3.0 spec.
For its current desktop platforms with DDR4 memory, AMD offers A-XMP, a UEFI firmware-level innovation that translates settings from XMP profiles into AMD-compatible settings. RAMP will be different, in that in addition to the usual memory clock-speeds, main timings, and voltage values, it will include many of the finer memory settings that are specific to the "Zen 4" memory controller.
"Raphael" Socket AM5 desktop processors will be AMD's second processor to support DDR5 (assuming it launches before EPYC "Genoa."). The company's Ryzen 6000 "Rembrandt" processors based on the "Zen 3+" architecture already come with a DDR5 memory interface. Socket AM5 is expected to be a DDR5-exclusive platform unlike Intel Socket LGA1700, which means no backwards-compatibility with DDR4.

I never knew such a job existed. Learn something everyday.
I was hoping this platform could also run ddr4 but it’s not looking like that. Hopefully jedec ddr5 speeds improve, but I can’t see them getting too high since most CPUs max out at 4.5ghz wo oc. I guess it would be good if ddr5 prices and availability also improved.
Everything AMD=:peace:
Everything Intel=:nutkick:
That is definitely the impression this forum gives now.
But anyway, lets see if AM4 can make me switch back again. I like new stuff, not regurgitated cud
Of course there are people who pick a side and stick with them.. which is somewhat unfortunate. But no need to rub anyones nose in it. Both brands have their own faults and none are perfect.. yet.
Intel on the other hand flexing by bending their chips. Absolutely hilarious. :laugh: And the deniablity, lol.
They made thermal paste obsolete, because at that flex it will be cooked/dried out in no time. Just use tooth paste.
Meteor Lake on the other hand will most likely be DDR5 only.
With DDR4, Zen2 and Zen3 really really benefitted from low CAS latencies and the fastest FCLK your CPU could handle.
CAS latency is so important that DDR4-3000 CL12 is significantly faster than DDR4-3800 CL17 in most scenarios and if you're deciding between two RAM kits, the one with the lowest absolute latency should be your first choice.

Was good enough for my near world record E6300 OC
Depends on what you need in terms of "real-world speed" - most things are perfectly good with a locked 12 ms frametime on variable-refresh displays, which is super easily achievable on Zen3/ADL.
Other things are more low latency focused, which makes them very stutter-sensitive. They want a stable, high framerate, without any massive distracting stutters (very low minimum FPS).
6.7% Increase in average FPS? Pretty meaningless.
17.4% Increase in low-FPS scenarios? Very nice.
68.9% Increase in minimum FPS? Incredible! (visible in a much less "pretty" graph)
