welcome back to harbor unboxed for today's video I'm finally able to expand upon the IPC testing feature in our day 1 coverage unfortunately I wasn't able to do any IPC testing with the 3900 X because this exact chip he actually died during my review of the new 3rd gen risin processor so if you want to hear more about that then feel free to watch that video but yeah this little guy here is dead but the good news is I do have a replacement now so I was able to go back and compare the IPC performance between a single chip lit with 8 cores enabled to a pair of chip alerts with 4 cores enabled in each one so all that testing will be in this video now that I have my replacement 3100 X so it's really time for some more in-depth IPC testing I think for those of you unaware IP C stands for instructions per cycle and it can be a good indicator of an architectures efficiency traditionally Intel's coffee-like CPUs have offered high IPC coupled with a high operating frequency that's really the best combination for maximum performance although AMD's still clearly trailing when it comes to frequency they do a pedo of really closed up and possibly exceeded Intel's IPC performance and that's likely why so many of you have been requesting this particular test to see just how much headway aim'd is made here we're going to neutralize as many variables as we can while also keeping things as realistic as possible the first and most obvious step is to remove the core frequency from the equation and to do this we've locked all CPUs at 4 gigahertz any type of boost technology has been disabled and this means no calls can clock past 4 gigahertz and all cores are clocked at 4 gigahertz then for the riser 930 900 X we've disabled two cores and each chip --let taking it from a 12 core part down to an 8 core part so all CPUs tested have 8 cores active but whereas the 3700 X has them all in a single die for 3100 X spreads them across 2 dies the third gen Reisen CPUs have been tested on the gigabyte X 570 or extreme using the latest bias which uses a g1 dot 0.3 a B then for the first and second generation CPUs they've been tested on their sous ROG crosshair seven hero and the coffee-like CPUs on the gigabyte z3 19 horas ultra all configurations use the same g.skill Flair X ddr4 3200 memory using the extreme memory profile and the same msi RT x 20 IDC a gaming extra was used for all the testing this is purely a for science type benchmark and is in no way buying advice the coffee like CPUs do have a clock speed advantage but that doesn't necessarily make them the best choice for gaming and real-world performance to find out which CPU should buy a please refer to our recent rise in 930 100x 3700 X and 3,600 reviews first up we have the Cinebench our 20 multi-core score and here the 3100 X and 3700 X provided roughly the same score making them both around 14% faster than the 99er ok when matched clock for clock moreover they were both 18 percent faster than 2700 X and that's a significant improvement in IPC performance here we see a 13 percent performance uplift for the third gen rising parts over the 2,700 X and this meant they were also 9 percent faster than the 99er ok so pretty incredible stuff for these new rise and processors here we see the jewel chip design of the 3100 x actually improves performance in the very benchmark by a 2% margin over 3700 X not a big difference really but it was consistently faster in this test this meant when matched at the same clock speed the 300 X was 6 percent faster than Intel's Core I $9.99 ok and 13% fast on the 2,700 X this time the 3100 X was 3% faster than the 3700 xmin looking at performance using the corona benchmark this made the 3100 X 5% faster than the 1900 K and 16% faster in the 2,700 X that's pretty impressive stuff but let's move on to see how things look in a few games the first game I'm going to look at is battlefield 5 and here we see despite a hefty reduction in clock speed the 99er case still manages to take out top spot the 1% low performance was still very impressive and here the 19 a hurricane was 9 percent faster than the 3rd gen rising processors when looking at the average framerate we see that the 3700 X was 8 percent fast and the 20 while the 30 100x was 13% faster this means that even when matched at the same clock speed with the same number of cores the 30 100 X is still 5 percent faster than 3700 X which is very interesting we see that the 1900 can takes out top spot this time in Far Cry New Dawn beating the 3900 X by a 5 percent margin for the average frame rate but it was 10% faster for the 1% lower result however what we should probably focus on here is the impressive step forward AMD has been able to make here the 30 100x was incredibly 20 percent faster than the 2700 X while the 3700 X offered a 16 percent performance improvement that's a very impressive generational leap even at 1080p with the RT X xx atti Total War Three Kingdoms is mostly GPU bound still we do see some improvements than 1% low results and again Intel comes out on top but as I've said we're mostly GPU bound here so let's just move on for those of you who missed my discussion regarding the World War Z results in my original 3rd gen rising content in short the game received an update that dramatically improves performance but for whatever reason the epic store didn't roll this update out to me for over a week after its initial release the good news is this update sees rise and processors performs significantly better and now the 3100 X is able to roughly match the 1900 ok in our IPC test again the dual chip tlit 1300 X was fast and the single chip alert 3,700 X this time offering a 4% bump for the average frame rate this meant the 3100 X was 14 percent faster than 2700 X while the 37 Rx was 9 percent faster another game that I decided to check out is World of Tanks and this game has been recently redesigned to take better advantage of core heavy CPUs interestingly when matched at the same clock speed the 3100 X provided better 1% low performance than the 99 or ok boosting performance here by a 4% margin though the average framerate performance was much the same the 3100 X was faster than the 3700 X improving performance by 4% this again made the 300 X 13 percent faster than 2700 X while the 3700 X was 9% faster than the 2,700 X the last game that we'll look at is Rainbow six siege and here the night ROK was a good bit at least when looking at the average frame rate I mean it was just 5% faster than the 39 Rx and eight percent faster the 3700 XO not a massive margin but it was still faster that said the one percent low performance was similar across the board and here we're looking at another mostly GPU bound game with these higher-end CPUs something I discovered when first testing the Rison 7 3700 X was the much lower than expected right memory bandwidth after speaking with AMD they filled me in on what's going on here basically AMD's made a compromise here as client workloads do very little writing so rather than use this space to improve something that isn't required or at least not going to be fully utilized they've invested this silicon real estate in more beneficial ways to achieve performance gains the end result being that the core complex data i/o die link for reading memory is 32 bytes wide but it's only 16 bytes wide for writing however because the 1,300 X has to see CDs it features two lanes from writing and that brings the peak bandwidth back up to around 50 gigabytes per second moving on to cache bandwidth and here we see the 3700 X and 3900 X are virtually identical and both offer substantial gains for l1 l2 and l3 bandwidth over the second gen Verizon 2700 X here we see l3 cache bandwidth has been increased anywhere from around 40 to 50 percent with the third gen rise and parts we also see a 30% improvement l2 bandwidth and an almost 100 percent increase in l1 bandwidth that's an incredible performance uplift and it certainly would go a long way in explaining why we saw a 100% performance gain in applications such as WinRAR as for memory latency well not much has changed here if anything we see an increase in memory latency from second gen Rison and we see this when looking at DRAM and l3 cache latency the DRAM latency is 50% higher than that of the kora 999 okay and this will be partly responsible for the difference we see in gaming performance another reason for the slightly lower gaming performance is called latency still when compared to second generalising the new third gen architecture is a massive improvement for the best match cause we're seeing a 30% reduction in latency and at least a 26% reduction for the worst cause or Maine's best case the cortical latency is actually reduced by 35% for the third generation processor when compared to the Intel coffee-like architecture and that's pretty good problem is worst case the latency is 54% higher and that really isn't very good especially when playing at latency sensitive games okay so it's pretty clear AMD's made a big step forward with third gen risin we really knew that from the moment we first tested the 3700 X and 3900 X we were also expecting good things especially after AMD well the world at Computex this year claiming a massive 15% uptick in IPC performance and they weren't exaggerating either with cos and clock speeds at parity the 3100 X provided an 18% improvement over the 2700 X in center benches multi-core test than 13% for the single core test we saw a 13 percent improvement in v-ray and then a 16 percent improvement in Corona and then when you average all that together that actually gives you a 15 percent improvement in IPC performance you can't really use games to measure IPC performance but they're still interesting to look at 4 o'clock 4 o'clock comparisons one obvious issue with games is that they're not always CPU bound and even when they are the degree to which they are CPU bound can vary for example we saw a very minor performance gains in rainbow 6 siege and Total War Three Kingdoms but in those two tiles we were obviously quite heavily GPU bound the 3900 X was between 13 to 14 percent faster than the 2,700 X when testing with World of Tanks World War Z and battlefield 5 and that's pretty close to AMD's 15 percent claim which again doesn't necessarily apply here then of course we saw a much more significant 20 percent performance improvement in Far Cry New Dawn given more time and actually like to go back and include a scar like X processor in these results that could be really interesting though probably makes sense just to wait for the third gen through her past at this point before making that comparison not sure about that one maybe let me know what you guys think in the comment section below and that is gonna do it for this one if you did enjoy the video be sure to hit the like button subscribe for more
