Intel Core Ultra 7 265K Memory Testing - CUDIMM vs UDIMM, 6400 MT/s vs 5600 MT/s

I have corsair dominator titanium 7200MTs CL32, do you now if that has cudim?

When can we get the benchmarks for this CPU variant against other CPUs? Because I am unable to find a benchmark for this CPU anywhere

R6 uses DX12 by default currently. 🙄

I'd be interested in seeing efficiency tests, not at stock as that can hide actual efficiency by some chips being pushed further past the most optimal efficiency point than others. Would be nice to to know how they perform at 35W, 65W, 95W etc (vs competition at same power limits)

We going to get 9800x3d memory test?

Clearly, latency matters.

The Intel CPUs do seem to be a little more RAM bandwidth and latency sensitive than the x3d parts, and that isn't much of a surprise when you consider all that L3 does make calls to main system memory less frequent.

Thanks for this clear breakdown.

Can you make a video on undervolting? I’m curious to see if we can get better temps and efficiency without having to sacrifice much performance

Were the good CUDIMM kits not available pre-launch for testers? That's a hilariously slow timing kit. I have a better kit in the computer I built in 2023. Of course it seems like it doesn't matter, you have middling speeds for this gen with various horrible timings. A 7200+ CUDIMM kit with tight timings would be incredibly impactful in many games compared to a 6400/52 kit.

Seems crazy to me to look and see 5% FPS spread across your mediocre kits from low to high and NOT concluding that the new fastest-possible kits which only work on the Intel platform wouldn't continue to positively affect performance. I'd bet right at a 10% performance gap between 6400/52 and 7600/36 CUDIMM. That's massive.

CUMMDIM ?

if theu upped the P-cores count to 12 it was gonna be the best i9 ever made

So cudimm start 300+ for 32 gb and thats not a issue?

Another clown testing in 1080p 🤦‍♂️

How does it handle Single /dual Tower air coolers?

I was hoping to have a good reason to upgrade from my 13900k. Not seeing it this generation.

Intels Ultra ( failure )

But how about workstation or creator workflow

😎👍

I saw that the kingston 9600 cudimm is sold out. I'm really curious how these chips will perform once things get sorted out. The z890 boards obviously need some work when it comes to the bios settings and windows scheduling needs work as well. If the underlying architecture has more potential than anything else out there, I wonder if Intel is suffering from bad business relationships in the software space. There is no doubt that they have capable engineers, but if they don't have support from management within the company, then business relationships suffer across the board.

I know that V-COLOR Manta XFinity RGB DDR5 48GB (24GBx2) 8600MHz CL40 1.45V CUDIMM works out of the box on Ultra 9 285K XMP2

Why run these slow ass Dimm sticks on a core ultra??? I'm running 8400 with DDR5 7600...

Turns out fairly few people were given a 265K! I'll have a full video up hopefully tomorrow comparing this to the 14700K, 7800X3D and 9700X - I only got those three on Monday so I've been working round the clock to test and verify the frankly insane results I'm seeing... Stay tuned!
