So we have new leaked R15 numbers from Alva(?) guy again (boy if it was him he is in trouble :S). Benchmark ran with the same 6C/12T ES, 3.3/3.7Ghz with 3.4Ghz ACT meaning the MT test was ran at 3.4Ghz. Of course take everything below with a grain of salt - it is still fun .
Let us compare with XV/SB-E/IB-E/HSW-E and BDW-E

Zen 6C/12T ES 3.3(3.4Ghz)/3.7Ghz
ST @ 3.7Ghz (ST Turbo) 146
MT @ 3.4Ghz (ACT) 1130-1140 (source baidu, same as for ST, both now deleted)
Both tests on 3.4Ghz would yield: ST 134 and MT ~1135(mean)
ST->MT scaling :
1135(mean)/134=8.45x => 8.45/6=1.4x or
40% SMT gain
Carizzo (Excavator) X4 845 3.5Ghz (base)/3.8Ghz (ST Turbo)
ST @ 3.8Ghz ~92
MT @ 3.5Ghz (base) ~314
Both tests on 3.4Ghz would yield: ST 82 and MT 305
ST->MT scaling :
305/92=3.71 => 3.71/2=1.86 or
85% scaling with CMT
i7-3930k SB-E 6C/12T 3.2Ghz base/ 3.8Ghz ST turbo
ST @ 3.8Ghz (ST Turbo)133
MT @ 3.5GHz (ACT) 907
Both tests on 3.4Ghz would yield: ST 119 and MT 881
ST->MT scaling :
881/119=7.4=> 7.4/6=1.23 or
23% SMT gain
i7-4930K IB-E 6C/12T 3.6Ghz base/4Ghz ST turbo
ST @ 3.9Ghz (ST Turbo) 140
MT @ 3.6Ghz (ACT) 959
Both tests on 3.4Ghz would yield: ST 122 and MT 905
ST->MT scaling :
905/122=7.42 => 7.42/6=1.23x or
23% SMT gain
5960x HSW-E 8C/16T 3(3.3Ghz ACT)/3.5
ST @ 3.5Ghz (ST Turbo) 140
MT @ 3.3Ghz (ACT) 1337
Both tests on 3.4Ghz would yield: ST 136 and MT 1377
ST->MT scaling :
1337/136=10.12 => 10.12/8=1.26x or
~26% SMT gain
5820K HSW-E 6C/12T 3.3(3.4Ghz ACT)/3.6Ghz
ST @ 3.6Ghz (ST Turbo) 140
MT @ 3.4Ghz 1025
Both tests on 3.4Ghz would yield: ST 132 and MT 1025
ST->MT scaling :
1025/132=10.72 => 7.76/6=1.29x or
29% SMT gain
6900K BDW-E 3.2Ghz(3.5Ghz ACT)/3.7Ghz (Anandtech bench)
ST @ 3.7Ghz 153
MT @ 3.5GHz ACT 1547
Both tests on 3.4Ghz would yield: ST 140 and MT 1502
ST->MT scaling :
1502/140=10.72 => 10.72/8=1.34x or 34% or
34% SMT gain
From above we can try and see what is Zen's IPC in R15 compared to:
1) XV
ST: 134/82=1.63x or
63% higher ST IPC for Zen Vs XV
MT (IPC+SMT): (1135 *4/6)/305~=
2.5x or 2.5x higher throughput core for core; if we think of the XV module in terms of a "core" than 1C/2T on Zen is having 25% higher throughput than XV 1M/2T. Results usually do not scale upwards perfectly when upping the core count so adding 0.95 penalty gives us ~18% higher throughput than XV module and 2.37x vs XV core.
2)SB-E
ST: 134/119=1.126 or around
12-13% higher ST IPC for Zen Vs SB-E
MT(IPC+SMT): 1135/881=1.29x or
29% higher throughput than SB-E core
3)IB-E
ST: 134/122=1.1 or around
10% higher ST IPC for Zen Vs IB-E
MT(IPC+SMT): 1135/905=1.25x or
25% higher throughput than IB-E core
4)HSW-E (8C/16T 5960x)
ST: 134/136=0.98 or around
2% lower ST IPC for Zen Vs HSW-E
MT(IPC+SMT): (1135*8/6*)/1377=1.09x or
9% higher throughput than HSW-E core. Note that at 3.4Ghz 16T HSW-E has 34% higher throughput than 12T HSW-E, meaning R15 scales almost perfectly from 6 to 8 cores with SMT.
5)BDW-E
ST: 134/140=0.957 or around
5% lower ST IPC for Zen Vs BDW-E
MT(IPC+SMT): (1135*8/6)/1502=1.007x or
about equal throughput for Zen Vs BDW-E core
edit reason:fixed XV MT scaling which was incorrect
