any time you use ram more than 4 GB that is part of the 64 bit change

64bit cpu not needed for that. See PAE.

The actual limiting factor (in x86 specifically) is that a single process view on memory is 32bit thus 4GB. This is specific to the design of the CPU; it's very well possible to get around that with techniques such as overlays or segmentation, as 16bit x86 demonstrated very well.

Then there's processors like the 68000, which offered a 32bit ISA with direct 32bit addressing (although only 24 exposed in the physical bus, until 68010 had versions with more address lines, and 68020 with full 32bit), despite 16bit ALU.

Similarly, SERV implements a compliant RISC-V in a bit-serial manner.

Of course, having 64bit GPRs specifically is very convenient past 4GB.

or having a file bigger than 4 GB

Large offsets are possible in 32bit too. In e.g. Debian Linux, it is common in all architectures other than x86.

or a disk partition that is bigger than 32 GB

32bit block addressing to 512 byte blocks yields 2TB.

And again, software can handle 64bit values in 32bit (even 16 and 8) architectures no problem. It's just slower and more cumbersome, but the compiler will abstract this away. For disk I/O addressing, it is a non-issue, as latency of the disk will make the cost of these calculations irrelevant.

The startup also has IP-licensing deals with companies, including LG and Korean automotive SoC maker BOS Semiconductor. Hyundai has also said it will use Tenstorrent tech across its portfolio. The company is also committed to building a CPU and R&D team in Japan, given the exceptional talent base in Japan, and Japan’s history of high-performance computing

Yeah, Tenstorrent's hit gold. Their IP is going to be everywhere.

It's not that simple.

Having L4 at all increases latency to actual RAM.

Oh, point.

But, of course, at 4070ti prices, I'd look at 7900xt.

[–] [email protected] 1 points 10 months ago (2 children)

7800xt is about the same (except a little better on RT and has av1 encoder). Some games, it's actually a little worse.

4070ti is better in RT, but similar (if not a downgrade) in raster. Not an upgrade either.

Traditionally, one generation is not worth it, unless you're going from low-mid end to high end. which is costly. Still applies today apparently.

I tend to HODL and only upgrade every 4-5 gens. Vega64 -> RDNA4 is my current plan.

6800xt

With that, I'd wait for RDNA4.

7800xt isn't much of an upgrade, nor is 4070ti.

Seems TSMC has chosen Asia (and Europe) over America, for its batch of new fabs.

Cool, their pcie ML accelerators are finally purchasable.

Now let's hope for Ascalon / Alastor devboards next year.

NVIDIA are no saints.

The simpler possibility of them actually stealing secrets is far more likely.

It wouldn't be welcome.

That ecosystem doesn't want binaries.

I love how they resurrected and maintain the DOS version still.
