there's not a whole lot of point to this video other than a lot of people kept asking for it this is a quick look at some of the benchmark performance for an Intel processor one before and after the Windows patch the security patch now here's why there's not a lot of point to the video the number one reason is that we're still waiting on Intel for microcode or firmware updates which will likely be pushed out with motherboard vendors support websites and on Intel's own Download Center this means that there could be changes from these numbers we're seeing today everything could be different the reason we're testing it today this is just an a/b test of before the latest Microsoft Windows patch for the security issue meltdown and potentially Spectre although that needs more work and establish a baseline before and after hasn't done anything before the firmware from Intel and then once that firmware comes out we can look at it again with a fuller picture and likely see the the results that would be more or less expected before that this video is brought to you by EVGA and the X 299 dark motherboard for the Intel high-end desktop CPUs the X 299 dark is one of the only motherboards on the market with proper vrm cooling we've tested this and found a significant performance increase over those without active cooling on the prm's this board was used in our recent attempt to set a top-10 record in fire strike and you can learn more about the x-29 dark at the link in the description below so it's still worth doing this test fortunately almost all of our CB testing is automated which means that it's couple button clicks and recording some data so we were able to run through the bench suite that we normally use and just validate note that these numbers are not comparable with previous CB benchmark numbers we've published because we're doing a few things differently different ram different OS different drivers all that stuff this was a very quick complete clean install brand-new windows install and then we tested with the version from december and the version from the other day and it's just an a/b test we're only doing 7700 K right now we've got CES in a couple days we're leaving so this is what we can do for now so let's just go through these quickly I guess you can expect the results pretty much at this point will be largely all the same because consumer workloads shouldn't really be affected too much by this latency change and then the the firmware will if any changes to be expected will be responsible for most of that as far as why this is all happening check out our video on meltdown inspector that'll get you up to speed on why we're here today and just quickly to note the reason any performance degradation would be expected at all is because theoretically because the meltdown fix requires introducing steps to check for vulnerabilities you're increasing your latency to move stuff around work with memory so theoretically you have a higher latency you might have lower performance as a result some numbers reported online were 5 to 30 percent performance deficit but note again that those numbers reported by gr security were for primarily one Linux benchmark and every number thus far reported for most stuff in the consumer space has been it's all the same we haven't seen much for production so we'll start with that and then go from there so for the 7700 K on the gaming 7 motherboard we first tested Cinebench with our automated suite we observed a score of 198 for single-threaded performance across all tests with differences inside of margin of error we also observed roughly equivalent performance for the multi-threaded test also inside margin of error for this particular application pov-ray placed us at 123 seconds elapsed on all multi-threaded render tests or about 554 seconds elapsed for the single threaded test this is basically a rendering benchmark so once again there's no change here this had us at about 20 128 to 2131 pixels per second multi-threaded and 472 to 473 pixels per second single threaded once again no appreciable change n1 which is within margin of error fire strike has a lot of variants but we run it a couple times firestrike had our FPS scores as on this chart again no change not even close to a change and times by showed the same no change between 16 to 99.1 9 to Windows version and 16 to 99.1 to 5 Windows version blender 2.78 a had us at 42 minutes render time with the GN monkeyhead test which is equal between both windows version tests we also observed 37 minutes for blender 2.79 and the monkey heads or about 47 minutes for the GN logo render and 3.79 once again no change even on this somewhat large time scale as for a few games we saw no appreciable difference in ashes of the singularity where we measure differences within a margin of error don't go running to Reddit with this 1 FPS difference though claiming that one is faster than the other they are well within test variants they are functionally the same watchdogs 2 also proved the equal the differences were functionally zero literally zero in the case of average FPS and nearly zero in the case of 1% and 0.1% lows finally civilization six times the complete turns is also about the same at 17 0.76 to 17 point 8 seconds per turn this is with invariance and our difference is 4 hundredths of a second at this point so we're back to the intro of the video what does this mean the answer is nothing all it means is that if you updated your Windows version for the tests we've done on the CPU we tested you can expect no change that does not mean that there is no change to performance following the patches and it does not mean that we can extrapolate anything and following the January I believe its ninth updates as that's when the major embargo lifts and not an embargo that we were included in by the way this is an embargo for hardware and software companies so we actually for once have no idea what is contained within that embargo we'll find out when you do so yeah again all we're seeing here is that the current Windows version doesn't have appreciable nor measurable different is between the most recent December version of Windows and although they weren't included in these charts comparing a couple of quick ad hoc tests versus our tests from before fall creators update again basically no difference so the windows update alone does not appear to have changed performance in these tests and games it's possible there are changes to performance in other tests and games however I would suppose that a lot of those are more likely the result of other changes to Windows outside of the security patch that Microsoft put out remember this is not a patch that contains only a fix for the Intel and AMD and whatever the meltdown inspector bug and these not really included in meltdown but you get the idea it contained a lot of other stuff too just like all Microsoft patches do so we won't know more until January 9th for now looks fine but there is plenty of room for that to change when the new firmware comes out or the microcode and whatever else may be done at that point so we'll see performance could always get worse it could also remain completely stagnant but there's no room to really speculate on that for now so we'll keep you posted we're gonna be at CES when the embargo lifts for the hardware and software vendors on what they're doing so we won't be able to test it immediately we will be able to talk with them at CES if the topic is still of interest and if we think they can actually provide an answer to any of the questions so stay tuned for that subscribe for it has always you got to store it on cameras access net to pick up a shirt
