Celeron J3455

Vegan — Sun, 28 Nov 2021 04:05:14 GMT

I was looking down my pointed nose at my Celeron J3455 to see Intel's integrated graphics are so slow that even a word processor is sluggish.

AFAIK the CPU is resistant to Spectre and Meltdown seen with more expensive processors. The CPU has 4 cores but no L3 cache.

B0/B1 revision
Stepping 9
4 cores 4 threads

I do not know if the CPU has been updated to minimize the impact of the side channel attack.

With only 12 EU the logic is slow to run the Windows Desktop Manager and applications. The HD 500 cannot even reach HD 3000 graphics performance.

one of the links was broken the other was an index of items

I was more interested in the new stepping as to whether mitigations are in the SoC

A different problem is with the SATA SSD performance.

Apollo Lake supports SATA III so why is my SSD running at SATA II speeds????

The best option for that is to check with the motherboard OEM for troubleshooting steps and confirm why the SSD is running at that performance. For future requests you need to open a thread per issue and since you don't have any questions related to the original request in this case, we will close it.

Please keep in mind that this thread will no longer be monitored by Intel. Thank you for your understanding.

It has come to my attention that my Celeron is one of the Meltdown Spectre affected models too
