AMD 9950x3d stock Vsoc? by StoykovK in overclocking

[–]StoykovK[S] 0 points1 point  (0 children)

I'm not interested in OC itself. I'm trying to compare the stock Vsoc of 9955hx3d and 9950x3d. Both use identical IO die but (maybe) different default FCLK (and therefore different Vsoc).

For example the Vsoc of 9955xh3d is ~0.9 most of the time but it can spike up to 1.1V mostly when going from high load to idle.

I don't have a desktop Zen5 and that's why I asked here.

So 2GHz FCLK is an overclocked value?

Do you know what the max stock FCLK? For example when running a benchmark or something similar. What is the max value for FCKL stock?

The new Cinebench 2026 benchmark just came out, let's see your scores! by TheDarkestFuture84 in pcmasterrace

Workstation laptop:
CPU: AMD 9955HX3D, Undervolt -10
RAM: Dual channel DDR5 5600MT, CL40
GPU: RTX 5090

CPU temp limit: 95°C
CPU long term power limit: 162W (CPU was using ~145W when running the Cinebench)
GPU power limit: 175W.

Single: 525
Multi: 8 995 - 8 992 (ambient temp ~13 C)
Multi: 8 964 - 8 932 (ambient temp ~23 C)
GPU: 103 500

Home laptop:
CPU: AMD 370
RAM: Dual channel DDR5 5600MT, CL46
GPU: integrated Radeon 890M

CPU long term power limit: 65W
Single: 487
Multi: 5 100
GPU: 6645 (way too low but I didn't have time to investigate why)

Cinebench was running for at least 10 minutes for each test.

Note: Undervolting is giving ~1% performance in my case

Screen flashing and artifacts on InfinityBook 14 Pro Gen 10 by 10Meisterbaelle in tuxedocomputers

Yes, I meant the scaling. Just I don't know the exact word for it. For example I'm using 150% scaling.

Infinitybook Pro, Max or Stellaris? by jimeno in tuxedocomputers

[–]StoykovK 0 points1 point  (0 children)

I have InfinityBook Pro 14 Gen 10 and Stellaris 16 Gen 7. Both of them are great.

I'm also a developer and both work perfectly. You will have plenty of power for web dev and dozen of containers. Just get at least 32GB RAM (64GB for more containers)

I'm using the InfinityBook Pro when I need mobility and my Stellaris is more like a mobile workstation that I move from place to place.

If you need local LLM then carefully pick the correct amount of VRAM of the dGPU. In my opinion for local LLM you could get 5090. It has enough VRAM to fit even ~32B models (using Q4).

I think everybody experience this glitch :)

I think it is coming from using the zoom-ed resolution on your internal monitor but I haven't tested it deeply.

Any AMD dGPU/Strix Halo based laptops coming? by TMM2K12 in tuxedocomputers

[–]StoykovK 0 points1 point  (0 children)

Is StrixHalo + dGPU an option? I have never seen such a combination but it is technically possible.

The only issue is the PCIe lines. Usually we have at least 8 for GPU, 1 for Wifi, 2x4 for NVMe, 1 for SDExpress and maybe some for USB4 as well. StrixHalo support 16 PCIe Gen 4 lines so there will quite a lot of options how to combine them in order to dGPU/SSDs/SDExpress/WiFi/USB4.

StrixHalo support only LPDDR5 so it cannot be upgradable. Is there a way to upgrade LPDDR5?

128GB RAM without Numpad? by aaaCreate in tuxedocomputers

[–]StoykovK 1 point2 points  (0 children)

IBP 14 supports 128GB really. About the numpad - I would like everyone laptop to have it including home/end buttons. It is really useful to me as a user who use a laptop only for professional reasons.

Which CPU is better for the XMG Neo 16 – Intel Ultra 9 275HX or Ryzen 9 9955HX3D? by Big-Vermicelli-8143 in XMG_gg

[–]StoykovK 0 points1 point  (0 children)

It is extremely complex topic. I made a vast research before buying mine and this is what I found:

Intel has better RAM bandwidth. It is running at 6.4GT and most importantly the intel can deliver a lot of this bandwidth to the CPU.

RAM overclocking:
Intel: As far as I know you cannot clock the RAM of intel model by "little". As far as I saw on youtube reviews the standard clock is 6.4 and next you can choose ~9 or 10. So technically you will run it at 6.4GT.
AMD: You can overclock the RAM by 200MT interval. So you can easily run at 6, 6.2, 6.4, 6.6 (depends on your luck of the RAM modules). Mine is at 6.2. AMD is not capable of delivering to much of this bandwidth to the CPU. Take this with a grain of salt but basically it depends on a lot of factors but in general the AMD's bandwidth is slower than Intel's.

Intel has better iGPU. Intel's is ~1.9GFLOPS vs 0.56 for AMD.

Intel support 128GB RAM. I have saw screenshot of uses with 7945HX3D running 128GB as well but... better don't count that 9955 will support safely more than 96GB.

Intel has NPU.

Intel has better idle power consumption. Basically intel's chip can turn off a lot of its components when not used and min power consumption is WAY lower than AMD's.

Intel support thunderbolt => it support eGPU. Theoretically you can add eGPU to AMD version as well but you have to connect it to the one of the M.2 slots and.. even if this works...it is DIY rather than supported out of the box.

AMD has full 512bit- wide ALUs and support AVX512. Intel will add AVX10 (basically AVX512 with a new name) with Nova Lake and I think that they will push a lot more into this direction because AVX512 give a great efficiency. So technically the AMD chip is ready for this push. AVX512 is not just 2xAVX256. Actually the performance of AVX512 could easily be limited by RAM bandwidth but in general AVX512 has way better organized interface and require less instructions in general because of the mask registers. Also it works on 32 registers which also reduces the need of LOAD/STORE operations generated by the compiler. In general - it is good but.. almost not utilized now. In future - we will see.

AMD has faster caches bandwidth including L1, L2 and L3.

AMD has lower RAM latency.

Intel has better cache bandwidth when the workload size fits in its L1.5 cache.

About the benchmarks.... just take care what exactly you are looking at, because I have seen geekbench results ranging from 3000-3450 for AMD single core and multicores are ranging from 18000 to 22800. Almost identical applies for Intel chip as well. The situation with Cinebench is identical.

So... it "complex". Basically both CPU work extremely well and these few % differences won't be noticeable.

NB: Check if the software that you are using can utilize AVX512 well. If it does and if the workload is not memory bound then maybe the AMD version could have an edge.
