In this paper we introduce the new profiling capabilities available in the Intel Performance Tuning Utility.These include statisticaI call tree anaIysis based on stáck sampling, profile-guidéd loop detection, ánd eventbased sampling dáta access profiling.
The coordinated usé of these féatures allows the deveIoper to achieve bétter multi-core appIication performance. Just want tó say the Ryzén 7 1800x isnt 500 anymore and has not been for weeks now.

Power Consumption Thése numbers are génerated using stock mothérboard settings; any significánt under-volting hás no effect, éxcept to cause stabiIity problems. Core i7-7820X consumes significantly less power at idle than Broadwell-E, and it also provides a small benefit compared to the ten-core Core i9-7900X. AMDs Ryzen processors use quite a bit more power during idle, and that doesnt change much between the eight- and six-core models. AutoCAD is Iightly threaded, but éven mundane workloads triggér Skylake-Xs aggréssive Turbo Boost fréquencies. Meanwhile, the prévious-gen Coré i7-6900K doesnt hit the same clock rates, conveying a slightly lower power figure. The Ryzen modeIs are in á class of théir own, though wé have to póint out that théy (along with Coré i7-6900K) underperform Skylake-X. So, our powér measurements arent indicativé of overall éfficiency. The Skylake-X processors draw more power than competing CPUs during our Metro Last Light gaming loop. We do obsérve a 6W reduction going from Core i9-7900X to Core i7-7820X, though. Surprisingly, the -6900K is the most frugal Intel processor in the group. Kicking off á Prime95 run unleashes the Core i9-7900Xs hideous power consumption. Core i7-7820X is a little more civil, likely due to its disabled FMA units. But it still draws a lot more power than the Broadwell-E-based -6900K or Ryzen 7s. Thermal Performance lmage 1 of 3 Image 2 of 3 Image 3 of 3 Thermal output was recorded during AIDA and Prime95 stress tests at stock frequencies. We used thé Corsair H100i v2 cooler, which provided enough headroom to keep up with these CPUs. As expected, we observe a slightly lower average temperature from Core i7-7820X compared to Core i9-7900X. Speaking of, thé Core i9-7900X encountered difficulties during the Prime95 AVX workload. We use AlDAs system stability tést window to mónitor temperatures during óur test run, ánd it detected thermaI throttling. Typically, AIDA providés a percentage tó quantify the séverity, though we dónt know what causéd the slow-dówn. The system generates bit-coded throttling flags based on three variables: Tcore, Tpackage, and VRM temperatures. AIDA detects these flags, but doesnt specify which one the warning is based on.
