I apparently did well last time, so here's my guess for 2030:
And for standard issue I'm going to assume a typical mid end gaming PC you will buy from like HP, Dell etc, or something you would build yourself that is not super high end on like say, a $2,000 budget. Basically something you build as an every day PC for gaming, but not aiming for Linux Tech Tips level of power either.
So here's what I'm thinking could be a fairly standard run of the mill PC:
- 5Ghz 32 core processor with 64 or even more threads, perhaps they will start adding more than 2 threads per core at some point
- 256GB of system ram
- 5TB SSD and 30TB spindle drive being a common config. SSD for OS/programs and the spindle for data.
- 64GB of video ram
12V only motherboards will also be mostly standardized. There will also be a trend towards smaller PCs in general, like SFF being more normalized even for gaming. Though that is going against the trend of GPUs... they seem to be getting bigger and bigger lol. I could see external GPU enclosures being common as really those are what take up the most space in a PC. They are already a thing but rather niche. Maybe some "gaming" monitors will even have ability to put a GPU in the monitor itself, and you just feed it with a new type of connection that will become standard by then. Something like Thunderbolt, but more standardized. Maybe USB 4 or 5.
As for what will be high end, I could see something like this being available:
512 core CPUs running at 4Ghz (lower clock speed for more cores). And perhaps an improvement to HT where there will be more threads per core, maybe 4 or even 8 threads per core, so like a 512 core processor would show up as like 2048 threads. It will have some kind of cheezy marketting name like "Superthreading Technology(TM)"
- 4TB of ram will be something you can actually put on a desktop board, servers being in the 10TB+ range. There will be a big trend towards server clusters that process AI related stuff. Like a cloud AI type thing.
- 12TB SSDs will be something you can buy, and I could see spindle drives reach a plateau but perhaps get other improvements on speed. Things like multiple independent heads or something. Maybe even platters that can spin at variable speed to match head speed to land at a right location faster or something. Basically they will somewhat try to compete with the speed of SSDs. I could also see a whole new tech show up, like non magnetic, and non flash, something totally new. But even by then it will not be very mainstream. It will be faster than flash but not yet available in high capacities due to some kind of scaling issue they still need to work out. Might see USB sticks with the new tech, but they will be very expensive like $200 for a 16GB stick, but it will be almost as fast as ram.
- 512GB of video ram will be something obtainable, but will be very niche, and multi GPU video cards will be a thing too (I think there are some already?), where it will have some advantages in games/CAD programs that can take advantage of it.
Well we'll see how I do in 10 years.

I will be 44 then. Yikes. I spent way too much time thinking this through tbh. It's always fun to try to guess this sort of stuff to see how close or far you get.
