No, not on a laptop with anything like a comparable number of cores.
Any x86 or Apple Silicon laptop that can match the DC-ROMA II in QEMU will need around three times as many cores -- if the task even scales to that many cores -- and will cost a lot more.
I tried compiling GCC 13 on my i9-13900HX laptop with 24 cores, and on Milk-V Megrez which is the same chip but only one of them (4 cores, not 8):
on Megrez:
real 260m14.453s
user 872m5.662s
sys 32m13.826s
On docker/QEMU on i9:
real 209m15.492s
user 2848m3.082s
sys 29m29.787s
Only just 25% faster on the x86 laptop. Compared to an 8 core RISC-V it would be slower.
And 3.2x more CPU time on the x86 with QEMU than on the RISC-V natively, so you'd need that many more "performance" cores than the either this RISC-V laptop has RISC-V.
Or build Linux kernel 7503345ac5f5 (almost exactly a year old at this point) using RISC-V defconfig:
VisionFive 2 (4x U74 in-order cores @1.5 GHz, similar to RPi 3)
real 67m35.189s
user 249m55.469s
sys 13m35.877s
Milk-V Megrez (4x P550 cores @1.8 GHz)
real 42m12.414s
user 149m5.034s
sys 11m33.624s
The cheap (~$50) VisionFive 2 is the same speed as an M1 Mac with qemu, or twice as fast as the 6 core Zen 2).
The 4 core Megrez takes around twice as long as the 24 core i9 with qemu. Eight of the same cores in the DC-Roma II will match the 24 core i9 and be more than three times faster than the 8 core M1 Mac.
