Nigger RAM isn't available in powers of 10, it's available in powers of 2. Stop being niggerlicious and learn how to count.

I can't imagine the performance hit from a CPU having to convert literally memory addressing into decimal whenever it tries to get data.

here is a handy cheat sheet:

1 PB is 1024 TB
1 TB is 1024 GB
1 GB is 1024 MB
1 MB is 1024 KB
1 KB is 1024 bytes
1 byte is 8 bits

Don't let that last one trip you up.

I can't wait to spend $1,000+ on a GPU so the games can still look like and run like shit because of UE5 ray tracing DLSS and frame gen.

That is if you can find a game worth buy and playing these days that needs a high end GPU.

I didn't pay anywhere close to that for my 4070 Super and it makes everything look gorgeous. I won't upgrade for at  least five years, if not longer. By then card prices should stabilize.

They certainly will stabilize, but you seem to imply that means they'll become less expensive? Apologies if I'm misunderstanding.

I just want accurate numbers (in the operating system at least). Don't tell me it's 16 gigabytes (16 billion bytes exactly) if it's actually ~17.2 gigabytes. Having both the decimal and binary prefixes is fine, or an option/toggle.

You do realize that at it's core, computing is just switching lights on and off really really really fucking fast, so of course it's going to be base two(on,off)

We did experiment with analog circuits way in the past, which would have multiple states at different voltages. But they were inaccurate because the power wasn't stable enough. I'm sure now we could probably revisit multi state circuits but binary is too prevalent.

Quantum computers still convert to binary at key points right? Granted I'm not really in the loop about how quantum computers work, I'm years away from getting a proper home ARM server as the Amperes Alta is way out of my price range, let alone ever interacting with a quantum computer.

If you think Intel's QA was slipping before, wait until Lip Bu Tam takes his scythe to the company. He's one of those "Why do QA when our customers do it for us?" guys.

Not less expensive, but actually closer to MSRP. If you are paying 1000 for a 5070 you're a sucker lol.

You're not paying anything for a 5070 because they're out of stock. A 4070 Super currently goes for close to $900.

Analog computing circuits exist, but the basic problem is that signal-to-noise degrades very quickly with continuous functions as opposed to on/off functions. Like if you look at a noisy square wave, it's easy to tell which regions are on and which are off.

Contrast with a noisy sine wave. Which points correspond to a value of 100?

So compared to digital circuits, analog circuits are necessarily bulkier, low-precision, and power-hungry. But they're very good at continuously varying things, so for certain applications, they're ideal.

There are already multi-state circuits. PCIe 6 uses PAM4 to send two bits at once. I don't think there's much available in consumer hardware; and even PCIe 5 requires fairly good signal quality, or else you'll have strange issues like der8auer's issues in his 5080 FE review.

I think that analog computing is not very useful - some engineering codes can generate very high/low intermediate values, especially if you have precision issues (consider lim x+->0 1/x). Even audio shies away from it lately due to cost issues.

12-core chiplets have 48 MiB L3 (from 32 MiB currently). They are skipping TSMC's N3 nodes and going straight to the high-clocking "N2X", possibly enabling 6+ GHz clocks.

2-Hi 3D V-Cache is possible (e.g. 48 + 96 + 96 = 240 total, vs. 32 + 64 = 96 total of a 5800X3D/9800X3D). It might only come to Epyc products.

There are two possible I/O dies for desktop: N3P and N6. The N3P version has 2x Zen 5 "LP" cores. It may have 8 CUs of RDNA4 and an NPU. Cheaper SKUs may use N6 with no low-power cores, weaker/no graphics, no NPU, etc.

There's chiplet and monolithic variants of Medusa Point. Monolithic should be cheaper:
N2P + N3P Chiplet = 12-core Zen 6 + 2-core Zen 5 LP (in the N3P chiplet) = 14 cores (12 + 0 + 2)
N3P Monolithic = 4-core Zen 6 + 8-core Zen 6C + 2-core Zen 5 LP = 14 cores (4 + 8 + 2)
8-16 CUs RDNA4 or RDNA3.5+ possible. Infinity Cache could be the key to make an 8 CU model perform a lot better.

There's "Medusa Point Little" (like Phoenix2 or Kraken) with 10 or 12 cores, and 4 CUs RDNA3.5+/RDNA4.

There's an even smaller "Bumblebee" = 2-core Zen 6 + 2-core Zen 6C + 2-core Zen 6 LP = 6 cores (2 + 2 + 2). Graphics = 2-4 CUs of RDNA3.5+/RDNA4. 2027 product, may be able to go on FP8 socket (cheaper), retains 128-bit memory controller.

Medusa Halo may come out late 2027. See screenshot for details:

TI sells a lot of analog circuits. They've got tons of uses, but there's just no point in trying to build a CPU out of them.
