That's really not a bad price for the performance, at all.
At 1080p that's acceptable for a while as well, and with decent power usage.

I did recently buy 7600X CPU PC only because of that CPU.
Reason is that this CPU is rank 18 of Passmarks single thread list of >3100 CPUs:

(I will do multi-months sequential computation starting soon)

Cool is that "perf stat singleProcess" confirms running at 5.3+GHz single threaded:

107,245,113,513 cycles # 5.440 GHz

7600X came in with 9176.2 gmpbench (single threaded integer only benchmark) place 2:

I did factor 100 decimal digit number RSA-100 in less than 8min, and RSA-140 in 11.1h with cado-nfs.py highly parallel integer factorizer:

My 7600X PC did cost 619$, base price, with 2x DDR5-5600 16GB replacing DDR5-4800 8GB, and additional Gen4 SSD:

(the 2nd DDR5 did raise Passmark memory mark from 3100 to >3500)

I got warning link about Ryzen 7000 burnout issues.

"AMD Issues Second Statement on Ryzen 7000 Burnout Issues: Caps SoC Voltages"
https://www.anandtech.com/show/1883...yzen-7000x3d-burnout-issues-caps-soc-voltages

I upgraded the 1.18 Bios that did not contain overheat countermeasures to latest stable 1.24:

Before, with 1.18 Bios, I did run with "PBO with Tjmax=85°C" setting in Bios at maximal 86°C in order to achieve really high single threaded and multithreaded Passmark results. After Bios upgrade that option cannot be set anymore, and with default Bios setting CPU does not go above 76°C anymore — but the performance from before the Bios upgrade remained in many different benchmarks.

Just did run Passmark on headless Ubuntu 22.04 desktop PC again, nearly 28000 multi-threaded CPU mark, and 4173 single threaded (I had seen 4222 before):
PassMark PerformanceTest Linux AMD Ryzen 5 7600X 6-Core Processor (x86_64) 6 cores @ 5452 MHz | 30.5 GiB RAM Number of Processes: 12 | Test Iterations: 1 | Test Duration: Medium -------------------------------------------------------------------------- CPU Mark: 27896 Integer Math 84058 Million Operations/s Floating Point Math 45137 Million Operations/s Prime Numbers 166 Million Primes/s Sorting 43883 Thousand Strings/s Encryption 20041 MB/s Compression 298394 KB/s CPU Single Threaded 4173 Million Operations/s Physics 2262 Frames/s Extended Instructions (SSE) 19959 Million Matrices/s Memory Mark: 3655 Database Operations 7501 Thousand Operations/s Memory Read Cached 40974 MB/s Memory Read Uncached 38006 MB/s Memory Write 26392 MB/s Available RAM 28655 Megabytes Memory Latency 50 Nanoseconds Memory Threaded 56283 MB/s -------------------------------------------------------------------------- Results submitted: [url=https://www.passmark.com/baselines/V11/display.php?id=5041914]https://www.passmark.com/baselines/V11/display.php?id=5041914[/url] Use ESC or CTRL-C to exit A: Run All Tests C: Run CPU Tests M: Run Memory Tests U: Upload Test Resul

So if you run any Ryzen 7000 CPU, you might want to upgrade your Bios in order to avoid CPU burnout.

Btw, Passmark benchmark software has to be bought for Windows, but "Linux, macOS and Mobile Versions are free":

I did measure power consumption of 7600x PC in headless mode.
Running "stress --cpu 12" power meter did show only 120W.
More interesting for me was measurement with "stress --cpu 1", which showed only 80W.

Why more interesting?
24 hours ago I started sequential computation single process with minimal duration of 75.4 days(!), details here:
https://github.com/Hermann-SW/9383761-digit-prime#readme
Basement ceiling photo without/with smartphone flash:

pi@pi400-64:~ $ ssh hermann@7600x uptime
 20:06:09 up 1 day,  2:32,  0 users,  load average: 1.01, 1.02, 1.00
pi@pi400-64:~ $

After the first 24h of computation power meter confirmed slightly less than 2KWh per day:

75 days means 150KWh in total, but for more than 12h a day roof top solar power produces more than 0.08KW, so more than half of the computation is green:
