Tested with lnt,spec2000 and some other internal benchmarks (same as on ARM)
Performance Regressions - Execution Time
lnt.MultiSource/Applications/hexxagon/hexxagon 5.95%
lnt.MultiSource/Benchmarks/Olden/bh/bh 5.07%
lnt.SingleSource/Benchmarks/Shootout-C++/lists 3.02%
lnt.MultiSource/Applications/sqlite3/sqlite3 2.18%
lnt.MultiSource/Benchmarks/MiBench/telecomm-gsm/telecomm-gsm 1.59%
lnt.MultiSource/Benchmarks/MiBench/telecomm-CRC32/telecomm-CRC32 1.54%
lnt.MultiSource/Benchmarks/BitBench/five11/five11 1.20%
lnt.MultiSource/Benchmarks/TSVC/Expansion-dbl/Expansion-dbl 1.19%
Performance Improvements - Execution Time
lnt.MultiSource/Benchmarks/PAQ8p/paq8p -16.27%
lnt.MultiSource/Benchmarks/VersaBench/bmm/bmm -3.78%
lnt.MultiSource/Benchmarks/BitBench/uudecode/uudecode -3.55%
lnt.SingleSource/UnitTests/Vectorizer/gcc-loops -3.31%
lnt.MultiSource/Benchmarks/ASC_Sequoia/IRSmk/IRSmk -2.30%
lnt.MultiSource/Benchmarks/Olden/perimeter/perimeter -2.07%
lnt.SingleSource/Benchmarks/Polybench/medley/floyd-warshall/floyd-warshall -1.68%
lnt.SingleSource/Benchmarks/BenchmarkGame/puzzle -1.20%
Again, no major change in lnt, and spec scores seem unaffected. Same as on ARM, I've seen improvements in other benchmarks.
