Intel's Forgotten i7 | i7-5775C

I3 i5 and i7 CPUs obey a relatively simple numerology the second generation of chips in Intel's core I series were given a number two at the beginning and this would go on for every generation that followed it was simple marketable easy to understand 3000 Series 4000 series 6000 series oh the five thousands those were Broadwell we don't talk about Broadwell [Music] Intel's 5000 series of CPUs were mostly made for the mobile market although it was the first series manufactured on the 14 nanometer process nodes that would go on to become the staple of Intel's micro architecture right up until the 11th generation Broadwell had little presence outside of laptops and very high-end desktops I plan on looking at Broadwell e soon but in the meantime I thought it was worth looking at one of the more Uncommon desktop CPUs only two skus in this category were released making use of the z97 motherboards released for the refreshed Haswell Devil's Canyon CPUs the I5 5675c and i7 5775c Mark something of a passing of the torch as 14 nanometer would go on to Define Intel's processors for the next several years the Broadwell chips were somewhat ahead of their time and yet they were based on the same socket as the previous generation and worked with soon to be obsolete DDR3 RAM the model I have here is the i7 5775c built to the then standard desktop CPU configuration of four hyper-threaded cores clocked at up to 3.7 gigahertz using turbo boost but with an unlocked multiplier for easy overclocking however in one area it marked a step down from the previous gen i7 4770k and 47.90k unlike those CPUs and virtually every other consumer i7 since the beginning it had only six megabytes of L3 cache instead of 8 megabytes the reason for this reduction is due to the presence of something new and unique to Broadwell over time a massive but relatively slow 128 megabytes of Ed RAM on board acting like a level 4 cache in certain games and applications this extra cache could hold some benefits over even newer chips and during my testing I ran each Benchmark with the Ed Ram enabled and disabled to see how big of a difference it makes alas cache is where the 5775cs advantages end as Intel's early 14 nanometer yields didn't handle High clock speeds particularly well and I was only able to overclock my sample to 4.2 gigahertz a good 300 megahertz short of my standard overclocking Target to allow broadweller Channel to shine I've paired it with an Asus Griffin z97m motherboard 16 gigabytes of DDR3 2400 a chunky salmon Tower cooler and an Nvidia RTX 3070 starting with valent as per usual the i7 5775c puts in a good showing it's 275 FPS Nestles is in between the six core 5930k and the flat quad core i5 4690k both of which have been clocked 300 megahertz above the Broadwell chip you may well have expected a better result from the 5775c and if you can find a sample that's overclocks better than mine you might get it but as it stands this seems like as good a result as I could hope for if you are curious about how much impact the level 4 cache has on performance it's actually pretty big after losing around 40 FPS the 5775c now only matches uh four gigahertz i7 7700 [Music] now this is what I call a decent results the 5775c trounces a lot of good CPUs in Battlefield 5 leaving the entirety of Sandy and Ivy bridge in the dust and even beating the cable Lake i7 7700 at over 150 FPS on average this is almost competitive with modern ryzen chips and with the right GPU more than enough to drive a 1080P or 1440p 144hz display from my testing without the 128 Megs of Ed Ram it appears that it's contributing a hefty 20 of those FPS which is nothing to turn your nose up at [Music] and Broadwell continues to impress in fortnite performance mode it's 254 FPS average and 100 plus 1 lows uh again more than enough to satisfy owners of even a 240Hz High refresh Monitor and also put it a good 15 above the only other 14 nanometer quad-core I've tested the i7 7700 disabling The L4 cache was weirdly impactful driving the average FPS down to below 200. this seems like an anomaly like I can't imagine why a level 4 cache would make a 20 difference except that it's not the only time in this video that it will occur [Music] [Applause] moving away from Esports titles and into the areas where quad cores start to struggle at least this time the CPU hasn't caused flight simulators Graphics to fall apart as it did with the g3258 but 5775c owners shouldn't expect a 60fps experience here the 48 fps averages of course still perfectly acceptable for our flight Sim and the one on point one percent lows are actually a lot better than some other chips I've tried disabling the cash here has virtually no impact barring a single frame Spike that sent the point ones down into the basement [Music] the 5775c continues to fly high in Spider-Man remastered at least without Ray tracing at 96 FPS it's functionally tied with the i7 7700 and only a small step behind the six and eight core Haswell ease yes it loses to the ryzen 5600x but that chip has half a decade of IPC improvements 50 more threads and five times more L3 cash it damn well better be fast The L4 cache is contributing a big chunk of that performance too as without it the 5775c would only manage about 86 FPS as for RT the Broadwell chip is still holding on as almost 60 FPS on average but there's a much bigger Gap now between this and basically any six core with avx2 like with fortnite the difference between running with and without edram is also inexplicably huge foreign cyberpunk is unfortunately One Step too far for the 5775c without RT enabled it can almost reach an average of 60 FPS pretty much identical to the i7 7700 and within a few frames of the old 6 core hddt chips alas almost everything below it is a quad-core or less and everything above it has at least six cores the Ed Ram lust run is about 10 slower but nothing earth-shattering the picture changes a little once Ray tracing is switched on the 47 FPS averages now a little better than the 7700 and More in line with some of the hedt chips turning off The L4 cache costs it about 15 percent [Music] although in the grand scheme of things the 5775 sees average of 71 FPS in Red Dead Redemption 2 is a mid-table score it's still not a bad result meanwhile the other 14 nanometer chip boasts a slight lead despite its 200 megahertz lower clock speeds at least it leaves the I5 4690k in the dust my phased withdrawal of Eldon ring continues the 5775c isn't quite a 60 FPS chip in this title but it's pretty damn close at over 57 FPS on average the 42 FPS 1 and 24 FPS 0.1 are dragging the average down and if only the CPU could overclock another one or two hundred megahertz maybe it would give a more satisfactory experience as it is it's not bad but all things considered I'd hoped for better the Ed Ram has basically bugger all effect in Alden ring amounting to about a two percent Improvement in performance that would probably vanish over a long enough time frame [Music] in fact those same disappointing results are repeated in The Witcher 3. once more the average just fails to hit 60 FPS as I ride through novograd with more appreciable frame drops even on my second pass right now I haven't got many other CPUs to compare in this title however the Ryerson 55600x is actually pretty close in price to a 5775c so maybe it's not all that unreasonable to compare the two the three FPS difference indicates that this game isn't really making serious use of The L4 cache either foreign 6 the 7.1 second average turn time is actually pretty impressive it's leaving behind not only the i7 7700 but also a bunch of older six eight and even 10 cores all by very very tiny amounts of course but these things add up if the 5775c had been released somehow without the 128 megabytes of Ed Ram that average turn time would have been a whole 0.04 seconds longer too [Music] [Applause] as a CPU then I'm kind of impressed and a little disappointed as the last gasp of socket 1150 and the first steps of the 14 nanometer process with a unique 128 megabytes L4 cache up its sleeve I'd hope that the i7 5775c could pull off a magic trick as it turned out the overclocking was underwhelming The L4 cache went a long way to compensating for this in some titles to the point where you might sincerely wonder why Intel haven't reintroduced it since then but in other titles it clearly makes no odds however Broadwell did have one last trick up its sleeve the thing most people who remember the 5th gen actually remember it for are better than average integrated GPU ta-da the Intel Iris Pro 6200 igpu was I guess a byproduct of Intel's attempts to make igpus that could stand up next to laptop discrete gpus as Broadwell featured in the their new retina lineup of Max Intel's focus on improving their igpus wasn't unexpected it was a bit weird that they bothered putting Iris Pro into an i7 for the PC Enthusiast market and then only to remove it from Skylake surely afterwards for testing I overclocked my processor's integrated Graphics from the stock 1.15 gigahertz to 1.25 in Intel XTU overclocking the Ed Ram is possible in the Bios but in my testing it actually resulted in a drop in performance which I obviously can't explain also thanks to a lack of dx12 0 or 12 1 instructions it can't run most of the games in either my CPU or GPU test Suites but here's what it could run [Music] we've already seen that without GPU constraints the i7 can push valent to many hundreds of frames per second however the iris Pro is going to put a stop to all that at 1080 High it struggles to hit 50 FPS and although I joke that pal region shouldn't care about 60fps that's less true of valorence when I dropped quality to low the game initially ran vsynced to 60fps despite every frame rate lock being disabled honestly it was a superb experience however I'm supposed to give you numbers so After figuring out how to disable vsync it's by changing to windowed full screen in case this ever happens to you I saw an average of 74 FPS with lows of about 50. for context and 11th gen i5's integrated Graphics scores about double this Battlefield 5 might be a bit old now and not all that demanding on Modern GPU Hardware considering how good it looks but to the iris Pro it might as well be cyberpunk a game which by the way refused to start at low settings and a conservative 50 resolution scaling the game can pull off a reasonably solid 30 FPS dropping scaling all the way to 25 breaks past 50 FPS on average but looks like a bad joke [Music] on the subject of bad jokes The Witcher 3 needed running in dx11 because the RS Pro doesn't support dx12 and even then the game still stutters at 720 lowest settings it can see a 20 FPS average but one percent lows dropped to single digits not the worst performance I've seen in this title recently check out my Pentium g3258 video for that [Music] the Old Faithful GTA 5 is many people's Touchstone for gaming performance and although I personally prefer to focus on newer games I do keep a drive especially for this game just in case I ever need to test a low spec GPU like this one at full 1080 with normal quality the game's not too smooth averages break past the 25 FPS mark But stutters occur frequently enough that it's a problem using two-thirds frame scaling seems to kick in a kind of semi-lock at 30 FPS similar to how valorent behaved and although this time I didn't figure out a way to get around it it seems like a much more playable experience than at full 1080. this was about the most insane Fortnight match I've had in a while and it's a real shame that I only had the iris Pro in the system at the time because I feel like with a more responsive setup I might have gone all the way at 66 percent of 1080 low using the dx11 API the game was running in the 30s and suffered from the usual poor frame pacing this was it turned out enough to get me 11 kills plus a couple of NPCs that got aggro by mistake but not enough for me to finish higher than fourth place [Music] it was running out at this point and I couldn't be asked to go back and test anything else but OverWatch 2 did present a small sliver of Hope at low settings and FSR performance it could hit a pretty decent 94 FPS average and would happily lock at 60fps if you so desired unfortunately it does make it extremely hard to tell exactly what's going on foreign there were to the iris Pro Graphics in 2015 igpus have come a long way since then and I think even a modern Intel's UHD Graphics would have no trouble putting out better frames than this for all the good work Intel put into the 5775c including some tech we could stand to see return in modern CPUs Iris Pro is best left in the past thanks for watching kindly do the usual YouTube things if you feel so inclined and I'll see you next time [Music] thank you
