Alder Lake-S leaks

Just thought I'd update from my last comment on this as have just come back and imported 351 images from today's corporate shoot. The whole import and 1:1 preview generation process took about 2 mins no more than 3. I forgot to start the timer but it certainly wasn't more than 3 minutes.

Really really fast. On the 6700K I would normally just minimise Lightroom and browse YouTube for a bit as it taxed the 8 threads of that CPU but I didn't need to wait around on the 12700KF it was just too quick lol. All 20 threads were being used and the temp didn't go above 61 degrees.

Absolutely excellent.

Glad it's working well and that you're happy :)

Interesting results. I've been thinking about upgrading my existing desktop for a few years now (6900k with 2666 ram), but the marginal benefits have so far outweighed the cost.

This is my existing system: https://www.pugetsystems.com/benchmarks/view.php?id=55043
The only LR benchmark for a 12700k I could find: https://www.pugetsystems.com/benchmarks/view.php?id=61483

On the active score (mostly develop tab), the 12700k is 12% faster. I can't say this would make much difference, and might be barely noticable.

However, on the passive score, the 12700k is a massive 50% faster. This is mostly importing and building previews, and then exporting again. This must mean that LR is also using the smaller cores for these tasks in addition to the IPC increase over the years. After this year's BTCC weekend I came home with over 7k raw files, and it did take a loooong time to build 1:1 previews (1h+) after importing them (maybe 10-15 minutes to copy from the memory cards and import). I generally export in smaller batches of 150-300 at a time and not full size so these typically only take a couple of minutes. The 12900k is about 77% faster in the passive tasks.

These sort of gains are centainly worth considering an upgrade.

50% more cores amounts to 50% more performance 5 years later.

The only time that LR uses all available cores/threads is during import and export. The actual image processing/develop stage is mainly done on the GPU with very little use of the CPU.
Import and export is actually even faster using a 3950x or a 5950x, simply because there are more cores/threads to do the job. Much the same applies to CAD/video editing, it's just that all the work is done on the CPU in this case.

I wonder how many people have just a CPU sat in a box and no board or RAM to complete the system.

This will be me tomorrow. 12900k in a sad little non-retail box.

I've ordered an EKWB CPU block which isn't due until the end of the month so I have at least a couple of weeks before needing to get anything else. Still really on the fence over the DDR4/5 thing. Have 32GB of Corsair Vengeance 4000 which would do just fine, but my board of preference is an Asus Hero simply because the VIII and XI have both served me well. Unfortunately that's DDR5 and they don't have anything similar for DDR4.

Might actually wait until after Xmas before seeing what my options are.

Better not be Asus z690 board (actually there is one gigabyte and one asrock that is also not compatible)

z690 boards in general have massive VRM and m2 heatsink and it has significantly reduced the available space for CPU coolers


At this rate, next gen motherboards will need to put the CPU socket on the back of the board so the cooler can go on the back and make cases wider to fit it
