Does anyone have metrics for some sort of benchmark per transistor? I wonder where the sweetspot is between something like these and SERV [1]. Obviously GPU wins on parallel math, but I wonder how much we are chasing in terms diminishing returns.

#172I'd love to replace my 2950x, but most desktop motherboards still don't support 128gb of memory.
No, a lot support 128GB. Some support 192GB or even 256GB: https://skinflint.co.uk/?cat=mbam5&xf=317_X670E&asuch=&bpmin...

You're comparing apples and oranges. Ryzen has never had the lead with 1T performance, but emphasises nT and core counts instead. Memory bandwidth is largely meaningless for desktop CPUs but matters a lot for a SoC with a big GPU. Strix Halo appears to be AMD's competitor to Apple SoCs which will feature a much bigger iGP and much greater memory bandwidth. When we hear more about that, comparisons will be apt.
Ryzen doesn't even lead in MT on laptops. With M4, they're likely to fall even farther behind. M4 Pro/Max is likely to arrive in Fall. AMD's Strix Point doesn't seem to have a release date.
I like what you're doing!
"M4 Pro/Max is likely to arrive in Fall." (no release date)

wait till china invades
As long as Biden wins the election, they won't. Because the US will defend Taiwan.
The real problem is, any disruption of Taiwan and China's ability to produce and sell semiconductors right now is going to have wide ranging impacts on the economy.
If you thought prices were high during pandemic shortages, strap in.
It's probably not a coincidence that as soon as the US starts spending billions to onshore semiconductor production, China begins a fresh round of more concrete saber-rattling. (Yes, there's likely other factors too.)

TBH, CPUs nowadays are mostly good enough for the consumer, even at mid or low tiers. It's the GPUs that are just getting increasing inaccessible, price wise.
Yes - with more and more users moving to laptops and wanting a longer battery life, raw peak performance hasn't moved much in a decade. A decade ago, Steam's hardware survey said 8GB was the most popular amount of RAM [1] and today, the latest $1600 Macbook Pro comes with.... 8GB of RAM. In some ways that's been a good thing - it used to be that software got more and more featureful/bloated and you needed a new compu…
To be fair, a decade ago gaming PCs came with 2GB to 4GB of vRAM. Today's gaming PCs come with 12GB to 20GB of vRAM. Most games don't demand a lot of system memory, so it makes sense that PC gamers would invest in other components.
You're also comparing Windows x86 gaming desktops from a decade ago with macOS AppleSilicon base-spec laptops today. Steam's recent hardware survey shows 16GB as the most popular amount of RAM [1]. Not the 5x increase we've seen in vRAM, but still substantial.

#176I wonder when the PC world will transition to unified memory and more monolithic architectures as seen in the Apple M-series chips, but also in the NVIDIA GB200 "superchip", the AMD MI300 accelerator, the X-Box and Playstation consoles, and even in some mobile phone system-on-a-chip designs. It feels like the PC is the "last holdout" of discrete upgradeable components with relatively low bandwidth between them. Soone…
How far back are you digging for calling the Internet a useless toy, the 70s? Profitable companies that provided internet like services existed at least as far back as the 80s.
I've seen this line pulled out before and it always seems like an assumption than actual reality.

> it used to be that software got more and more featureful/bloated and you needed a new computer every 3-5 years just to keep up.
I'm sorry, "used to be" ? 90% of the last decade of hardware advancement was eaten up by shoddy bloated software, where we now have UI lag on the order of seconds, 8GB+ of memory used all the time by god knows what and a few browser tabs and 1 core always peaking in util (again, doing god knows what).

I would prefer that we figure out how to make the massive vector blobs called AI work more efficiently, versus throwing tons of hardware at what we can barely understand in perpetuity. It doesn't sit right with me that putting lots of floating point ability in edge devices for running these approximate-at-best models is considered the way forward for computing.
Yeah, bitnets already shift those matmuls to integer math.

These processors will use the existing AM5 socket, so they fundamentally cannot make major changes to lane counts and allocations, only per-lane speeds. They're also re-using CPU's IO die from last generation and re-using the same chipset silicon, which further constrains them to only minor tweaks. Typical use cases and motherboards give an x16 slot for graphics, x4 each to at least one or two M.2 slots for SSDs, and…
Cheap small computers with Intel Alder Lake N CPUs, like Intel N100, allocate frequently a single PCIe lane for each SSD slot. However you are right that such a choice is very unlikely for computers using AMD CPUs or Intel Core CPUs.
with pcie 5, 2x is almost certainly enough for all but the absolute fastest drives.

> There is no difference between Intel and AMD Zen 4 for most 512-bit AVX-512 instructions. Except for the fact that Intel hasn't had any AVX-512 for years already in consumer CPUs, so there's nothing to compare against really in this target market
The comparison done by the AMD announcement and by everyone else compares the Zen 5 cores, which will be used both in their laptop/desktop products and in their Turin server CPUs, with the Intel Emerald Rapids and the future Granite Rapids server CPUs. As you say, Intel has abandoned the use of the full AVX-512 instruction set in their laptop/desktop products and in some of their server products. At the end of 2025,…
> of the high-performance programs that is possible in 512-bit AVX-512 due to the equality between register size and cache line size, so the consumer Intel CPUs will remain a worse target for the implementation of high-performance algorithms.
Can you elaborate here? I love full-width AVX-512 as much as the next SIMD nerd, but I rarely considered the alignment of the cache line and vector width one of the particularly useful features. If anything, it was a sign that AVX-512 was probably the end of the road for full-throughput full-width loads and stores at full AVX register width, since double-cache line memory operations are likely to be half-throughput at best and a doubling of the cache line width seems unlikely.
