    Ok from what I could read (https://www.reddit.com/r/hardware/co...nm_vs_amd_7nm/) the 7nm vs 10nm etc is largely marketing speak.


    First of all, "AMD 7nm" isnt exactly the correct term because AMD does not manufacture their own 7nm dies. In fact, the company that was spun-off from AMD due to mismanagement issues, now called GlobalFoundries, have halted all the R&D and plans for 7nm, and stick with the older 14nm tech instead for god knows how long.
    "AMD 7nm" is akin to saying "Samsung Android". Samsung just produces hardware that happens to run Android, while Android itself is made by Google. 7nm AMD chips will be manufactured by TSMC, the same one responsible for producing Apple, Qualcomm, Nvidia, and various other chips.
    Now that we got the basics out of the way, when it comes to Intel 10nm vs. TSMC 7nm, the TSMC has slightly denser die. However, the difference is so narrow, that in the end its a matter of which architecture (IPC) is better, and which can clock higher. Those two would have a much larger impact than the density itself.
    As others have said, the 10nm or 7nm name are pretty much marketing number these days.

    I'm not sure what they mean by saying marketing speak. Are they referring to the 7nm not being 7nm or are they referring to AMD that uses chips from TSMC? Because in the end it is AMDs design at 7nm. It is the pipeline size isn't it? It affects how many chips you can have per platter.

    From what I can figure out the term 7nm for "AMD" is close to what Intel calls their 10nm. If you look at the picture you can see size wise they are close to the same. So its ULED vs QLED etc :P

    It’s important to note though that while Intel is still on a 14nm node and AMD is set to launch their 7nm processors very soon, this doesn’t mean AMD’s will be twice as fast. Performance doesn’t scale exactly with the transistor size, and at such small scales, these numbers aren’t as precise anymore. The way each semiconductor foundry measures can vary from one to another, so it’s best to take them more as marketing terms used to segment products rather than exact measurements of power or size. For example, Intel’s upcoming 10nm node is expected to compete with TSMC’s 7nm node, despite the numbers not matching up.

    I think people are missing the point though. AMD is in this position because the reduced transistor size gives them the ability to push more cores per cpu die. 7nm by itself doesn't do anything. It's the same as people calling ray tracing RTX only because nvidia coined the term. The RTX feature set is infact DLSS and Ray tracing done in real time or rather denoising done much faster than with conventional cores.

    If Intel also had 7nm they could also up their core count but architecturally they haven't done anything to improve their performance that much.

    What kind of nonsense is this? "it's not AMD 7nm"

    We know Tsmc makes the chips but come on.

    When Intel moves to their 10nm they should be have decently better performance compared to amds 7nm, if not then they messed up.

    Seeing some benchmarks are starting to peek.

    Those numbers has no meaning to me tbh. Need to see gameplay numbers.
