| 44 | # most platforms; | |
| 45 | # (ii) as it can be seen, SSE2 performance is too low on legacy | |
| 46 | # processors; NxSSE2 results are naturally better, but not | |
| 47 | # impressively better than IALU ones, which is why you won't | |
| 48 | # find SSE2 code below; | |
| 49 | # (iii) this is not optimal result for Atom because of MSROM | |
| 50 | # limitations, SSE2 can do better, but gain is considered too | |
| 51 | # low to justify the [maintenance] effort; | |
| 52 | # (iv) Bulldozer actually executes 4xXOP code path that delivers 2.20; | |
