Intel Core Ultra 200 Series "Arrow Lake" to Support 10,000 MT/s DDR5

Sep 18th, 2024 02:46 Discuss (23 Comments)

According to the latest leak on the Chinese platform Weibo, Intel's upcoming Core Ultra 200 "Arrow Lake" desktop CPUs could potentially reach between 8,000 to 10,000 MT/s DDR5 speeds. To put this in perspective, Intel's current Raptor Lake Refresh processors struggle to reach 8200 MT/s, even with the best memory kits. It's also a big step up from the rival AMD, whose 9000 series chips usually peak around 6400 MT/s. CUDIMM technology, introduced earlier this year, incorporates a clock driver that regenerates the clock signal, enhancing stability and allowing for higher memory frequencies. Hence, the newest DIMMs are able to push to much higher MT/s with emerging platforms like Arrow Lake.

While it remains to be seen whether Arrow Lake CPUs will support 10,000 MT/s memory speeds immediately upon release, the trajectory of development suggests that such speeds are achievable shortly. Memory manufacturer Asgard recently unveiled CUDIMM modules humming along at 9600 MT/s, hinting at the potential. Motherboard makers aren't sitting idle, either. Leaked specs for ASRock's upcoming Z890 Taichi board tease support for memory speeds up to 9200 MT/s in specific configurations - a 2000 MT/s increase from its predecessor.

Memory speed support means nothing, imo. How fast and efficient it is during normal use is the only thing that matters.

For many creative tools its volume thats equally or even more important so waiting to see if finally people can have all 4 slots filled and have decent speeds(instead of reverting to JEDEC speeds).

* +Latency matters. For some matters if there is a noticeable FPS difference with a more costly RAM kit of the same size.

Faster speed is always a welcome but what is the native speed the of the arrow lake? Most people will opt for slightly faster than native speed over the fastest ram available… most likely due to cost… fastest ram is gonna be very pricey

It’s better to buy a slight faster than native speed of the cpu with a tighter timing..

I've yet to find out if CUDIMMs are a drop-in replacement for standard UDIMMs or if there is extra support necessary on the motherboard or CPU/IMC.

Even JEDEC speeds doesn't necessarily mean 4800. Might be 5600 or even 6000 if that's going to reliably work at 1.1 V.

They are supposed to be compatible. Anandtechhad a detailed report.

It's all backwards compatible (the difference is a chip on the memory stick itself) so you can drop in the fastest kit available into an old system... but it won't work at the advertised speeds because neither the CPU nor the M/B support that speed. So realistically you can stop worrying because unless you buy Arrow Lake or something further down the line, the kit will be useless anyway. It might even be effectively useless with Arrow Lake, we are all yet to find out.

It won't nearly reach the advertised speeds but it may have a small edge over what the same CPUs can reach with normal UDIMMs. Even in the weirdest of setups, such as 2DPC. Or Ryzen. Or Ryzen with 2DPC.

The entire system for transmitting data (IMC-wires-RAM) is not a strong chain with a single weakest link, it's a chain all made of weakest links. Making the clock signal cleaner may do wonders even on a slower system. I also hope the CUDIMM technology expands to lower speed modules, such as 6600 or 6400, which have become relatively cheap by now.

Right "could potentially reach between 8,000 to 10,000 MT/s DDR5 speeds", which could translate into a 1% or a 15% performance gain.
Another convoluted way of saying "we really don't know at this point'.

It can also translate into a 0% performance gain depending on the rest of your system and the program used.

Solid State Brain

In some fields (e.g. LLM inference), memory bandwidth is almost everything, and even 10000 MT/s dual-channel DDR5 memory would still not be fast enough. Quad channel memory (overall bandwidth in the 275-300 GB/s range) would start to become interesting and be a viable alternative to GPUs, though.

Every new generation intel is talking about new greater memory speeds and in reality they often lie.

Pics or it didnt happen.

That's one of the reasons LPDDR will become more common. Removable LPCAMM modules are also an option but anything that gets between the CPU and memory chips is an obstacle to high bandwidth.

What do you mean they lie? Every new gen (from either side) supports faster memory. It's all there in the specs.

Is this 10000 the same as 8000 was where even Buildzoid could not get it stable?
If so then it's good enough to run some benchmarks but not for 24/7 operation.

Anything above JEDEC specs is always considered overclocking. Because of that, speeds above JEDEC specs will always be hit or miss. Because of that, I always appreciate designs that can offer peak performance without requiring RAM so fast that it hasn't been standardized yet.

Not if it requires 1.6V.

I was wondering that myself when I first read about these new CUDIMMs. I might have to buy one for my Apex Encore. Test the limits of this 13900KS.

Looks to be well within DDR5's capabilities if there is sufficient cooling. These new kits will likely be engineered for this range

All I want is Dual Rank 1DPC memory at 6400 MT/s. It doesn`t need to reach 8000 MT/s+.

Really, they would have to be damned good memory chips to handle that 24/7. Imagine price.

I'll stick to very nice 7200 CL32 or lower (when available)

A few weeks/months before release they tell their customers about the better overclocking capabilities and later, after you bought it, there is not much left.

Again, overclocking is never a guarantee. When Intel or AMD talk about overclocking they are talking about potential.
