Why ThinkPad x1 carbon keeps using ddr3? I think it's the biggest issue of this laptop.

AMD (include new mobile Zen3):
+:
Best perfomance in multi-thread applications
-:
1. No USB4.0 (aka TB4.0/3.0).
2. No pci-e 4.0
3. No AV1 decoder
5. Bad H265/Vp9 decoder (hybrid, not 100% hardware) in 2.5k+ especially. It have always drop V-sync for video in 50-60fps and huge cpu load.
4. No HDMI 2.1 (4k/120Гц 30-36bits 4:4:4 output) and Display Port 2.0 (8k/60Hz/30-36 bits monitors).
5. Bad memory performance - very huge memory latency vs Intel. Typical drop ~ -30% in atomic operations.
6. No neuroDSP.
7. Lower single-thread performance vs Intel for same year production.
8. No AVX512
9. x8 pci-e 3.0 dGPU link in H series.

Intel:

+:
1. USB4.0 (aka TB4.0/3.0). 2x2 scheme (2 left side, 2 right-side). With Ice Lake.
2. AV1 decoder.
3. HDMI 2.1 (by official presentation).
4. pci-e 4.0 (x16 link to dGPU, AMD
5. Better single-threaded performance.
6. Best memory performance by latency - up to x1.5 vs AMD.
7. NeuroDSP (V1.0 in Ice Lake, V2.0 in Tiger Lake+).
8. AVX512
9. x16 pci-e 4.0 link to dGPU in H series.
10. Much better H265/VP9 decoders. Low cpu usage. Stable framerate.

-:
1. USB4.0(TB4.0/3.0) ports for many cheap laptops deliberately and despicably not  installed for marketing idiotic reasons. Because of this, laptops with Intel instantly lose their key advantage, for which Intel hardware buyers are forced to pay anyway, but the ugly marketers do not allow them to use ... Although the TB3.0 output costs a penny in terms of the cost of wiring on motherboards, i.e. to. all logic is already in SoC

2. DP2.0 is 100% fake (and 8k monitors) in Tiger Lake.

3. Very bad multi-threaded performance (and specially for one $ and one watt). Which leads to the need to overstate the consumption and leads to increased noise from the cooling system.

I will go as far as saying that *if* we don't get stronger AMD offerings this year, then the ARM chips like the ones already featured in the latest Apple Macbooks will be the final nail in the coffin of Intel's architecture -- just see how much power efficient they are will still outperforming the similar Intel CPUs. Why go down the path that kills x86 as a whole when AMD is still competitive in that front?

You can lower the score of the latest Lenovo ThinkPas X1 Extreme (Gen3) by at least 10 points as the outdated Intel i7-10750H 14nm+++++++++++++ is 32% slower than the AMD Ryzen 7 4800H.

Alternatively the Ryzen is 47% faster on average.
You cannot trust NBC who give 100% marks for such a slow Intel processor.

Intel is a dead brand since 2020 whose intentional market abuse and complacency resulted in AMD delivering innovation that customers asked for.

I hope that Taiwanese manufacturers like Acer, Asus and Gigabyte improve their keyboards to make it easier to switch away from stagnant mainland Chinese brands like Lenovo who are still bringing out inefficient, slow CPUs nobody wants.

Why are manufacturers so resistant to adopting AMD in their premium offerings? As a consumer i want this, just no options available.

Lenovo has improved the CPU performance of the current ThinkPad X1 Extreme, but the Intel CPU is still inferior to AMD's current processors. The X1 Extreme Gen3 is a very good multimedia laptop and we especially like the excellent keyboard, but there is still room for improvements for upcoming iterations.
