WEBVTT 00:00:00.240 --> 00:00:06.960 now i had originally intended to do using the imac with Windows and a 00:00:04.880 --> 00:00:13.120 top-tier mobile graphics card performance showdown with the Radeon r9 00:00:09.480 --> 00:00:15.040 m295x 8 gig yes actually 8 gig versus 00:00:13.120 --> 00:00:20.400 NVIDIA's king of the hill gtx 980m mobile as separate videos but my wife 00:00:18.400 --> 00:00:23.600 and the rest of the internet complains that we've been doing too many 00:00:21.520 --> 00:00:28.400 multi-part episodes so here they are together you won this battle but not the 00:00:26.320 --> 00:00:31.840 teaser battle my gs30 stealth external graphics card notebook review is coming 00:00:29.760 --> 00:00:31.840 soon 00:00:37.920 --> 00:00:45.120 experience silent performance with the new cooler master silencio 652s 00:00:42.480 --> 00:00:48.320 minimalist design maximum compatibility click now to learn more 00:00:48.719 --> 00:00:54.559 so bootcamp is freaking awesome you just 00:00:52.079 --> 00:00:59.199 spotlight search bootcamp assistant pop in a usb thumb drive point it at an iso 00:00:57.360 --> 00:01:04.960 then it walks you through resizing your os 10 partition creating a Windows one 00:01:01.440 --> 00:01:07.840 and then without any preboot f8 nonsense 00:01:04.960 --> 00:01:11.520 it runs the setup process all the while restarting automatically into the 00:01:09.439 --> 00:01:14.960 correct thing then finally you land on the Windows desktop you're prompted to 00:01:13.040 --> 00:01:20.479 install all the necessary drivers from one executable it reboots again and boom 00:01:17.759 --> 00:01:24.560 you are ready to rock the experience is so seamless compared to when i've dual 00:01:22.479 --> 00:01:27.759 booted in the past although admittedly it's been a while i have so many drives 00:01:26.479 --> 00:01:31.280 that i rarely see the point in partitioning for multiple os's accepting 00:01:29.680 --> 00:01:35.200 cases where the extremely limited upgradability 00:01:32.880 --> 00:01:39.520 of a particular machine forces me to do it now i've had a lot of people ask me 00:01:37.360 --> 00:01:44.000 to comment on what it's like to run Windows on a mac and frankly i don't 00:01:41.920 --> 00:01:50.399 know what they were expecting macs are not made of dragon scales and the force 00:01:47.439 --> 00:01:55.200 or whatever so it's exactly the same as running Windows on a pc with the same 00:01:52.479 --> 00:01:59.920 specs as that mac i cannot stress this enough there is nothing about a knack 00:01:57.840 --> 00:02:05.040 that makes it special other than subjectively beautiful industrial design 00:02:02.560 --> 00:02:10.000 driver validation and component quality control are arguably important things 00:02:07.119 --> 00:02:14.319 but they don't affect performance oh and i guess there's a little bootcamp doodad 00:02:12.480 --> 00:02:18.959 in the system tray that lets you reboot directly to os 10 if you want now the 00:02:16.879 --> 00:02:24.080 astute among you may have noticed that asterisk on the exactly about 40 seconds 00:02:21.840 --> 00:02:28.720 ago what was that thrown in there for well a couple of reasons first and 00:02:26.400 --> 00:02:34.319 foremost is that for anything to perform exactly the same it has to not be 00:02:31.440 --> 00:02:38.720 hamstrung on a normal pc with a separate tower and monitor a 4970k 00:02:36.800 --> 00:02:43.040 will typically operate at anywhere from four gigahertz to 4.4 gigahertz 00:02:41.040 --> 00:02:47.120 depending on how multi-threaded a workload you're throwing at it thanks to 00:02:45.360 --> 00:02:53.680 turbo boost which you can learn more about here on the imac thanks to the 00:02:50.239 --> 00:02:57.920 quiet but not particularly powerful 00:02:53.680 --> 00:03:01.120 cooling system that CPU idles around 50 00:02:57.920 --> 00:03:04.000 degrees ramps up to 80 degrees in under 00:03:01.120 --> 00:03:09.120 10 seconds then in spite of the fan ramping up aggressively at 30 seconds 00:03:06.560 --> 00:03:16.080 begins to thermal throttle at 40 seconds hits 100 degrees at 50 seconds and stays 00:03:12.959 --> 00:03:18.560 there operating anywhere between 3.6 to 00:03:16.080 --> 00:03:23.840 4 gigahertz with a multi-threaded workload about a five to fifteen percent 00:03:21.680 --> 00:03:29.680 reduction in the performance that CPU could achieve in something like you know 00:03:26.720 --> 00:03:34.720 uh multi-core video rendering if it had a better cooler it really raises the 00:03:32.319 --> 00:03:39.120 question why did apple bother to give users the option of a top tier chip like 00:03:37.120 --> 00:03:42.400 this when it was never going to reach its rated speeds when it matters most 00:03:41.440 --> 00:03:47.280 anyway the other reason my asterisk was put in 00:03:44.879 --> 00:03:51.200 there is something that i was very very 00:03:48.400 --> 00:03:54.959 very disappointed by not a lot of these 5k imacs are out there in the wild even 00:03:53.519 --> 00:03:59.200 fewer of them are running Windows so there wasn't a ton of information about 00:03:57.920 --> 00:04:05.280 what i'm doing here and i had to discover for myself that thanks to 00:04:02.480 --> 00:04:09.599 some combination of AMD's driver AMD's hardware and apple's custom timing 00:04:07.920 --> 00:04:16.959 controller that enabled them to deliver a 5k single tile display in Windows you 00:04:13.040 --> 00:04:19.680 will be limited to 4k resolution max so 00:04:16.959 --> 00:04:25.120 that's 3840x2160 on your 5120 by 2880 display something 00:04:23.280 --> 00:04:28.639 that doesn't seem to be bothering this fella in the apple community discussion 00:04:27.280 --> 00:04:33.120 thread where folks are saying they've been bounced around between apple and 00:04:30.880 --> 00:04:36.000 AMD and at one point someone says he or she was told to talk to microsoft about 00:04:35.120 --> 00:04:40.960 it but it bothers me a lot 00:04:38.720 --> 00:04:45.479 thanks to the much higher resolution than normal and much higher pixel 00:04:42.720 --> 00:04:49.440 density than normal of this display the approximations that come along with any 00:04:47.600 --> 00:04:53.759 non-native resolution operation of a monitor and lcd monitor be specific can 00:04:52.000 --> 00:04:58.560 be more accurate than they otherwise would be but there is still 00:04:56.000 --> 00:05:02.720 discoloration and blurriness on text that makes everything look a little 00:04:59.919 --> 00:05:07.199 fuzzy what a disappointment so the only real new information i have 00:05:05.120 --> 00:05:11.919 since my previous videos on the 27-inch retina 5k imac is that it thermal 00:05:09.600 --> 00:05:17.520 throttles while performing CPU intensive tasks seemingly by design since apple 00:05:15.039 --> 00:05:24.240 avoids ramping the cooling fan up for as long as it can before finally giving in 00:05:20.800 --> 00:05:27.120 and cooling that poor CPU and it cannot 00:05:24.240 --> 00:05:31.280 run its display at 5k in a native Windows environment which coupled with 00:05:28.800 --> 00:05:36.880 the fact that it also can't be driven as an external display on another pc or mac 00:05:33.919 --> 00:05:40.880 makes this machine optimal for very specific people so with that mini 00:05:39.360 --> 00:05:45.600 conclusion out of the way we can move on to the next segment of this video the 00:05:42.479 --> 00:05:48.960 performance of the r9 m295x versus 00:05:45.600 --> 00:05:50.720 NVIDIA's gtx 980m first a bit about the 00:05:48.960 --> 00:05:56.479 m295x a GPU that has only shown up in this 00:05:53.919 --> 00:05:59.680 imac in its top tier configuration so far to my knowledge although i'm sure 00:05:58.080 --> 00:06:04.960 someone in the comments will correct me if i'm wrong it's based on the same 00:06:01.600 --> 00:06:07.600 tonga architecture as a desktop r9285 00:06:04.960 --> 00:06:13.199 but with 14 more stream processors and texture units and an 8 reduction in core 00:06:10.560 --> 00:06:18.880 clock with the same 256 bit memory bus but in the case of this computer anyway 00:06:15.520 --> 00:06:21.280 it features a massive 8 gig frame buffer 00:06:18.880 --> 00:06:25.039 versus the 2gig one on its closest desktop equivalent presumably because 00:06:23.360 --> 00:06:30.560 apple felt it needed it to drive the retina imax 5k display not that it kept 00:06:27.919 --> 00:06:34.080 os 10 yosemite from frequently stuttering while switching desktops are 00:06:32.160 --> 00:06:38.720 using mission control anyway but today's video was not about running the imac in 00:06:36.080 --> 00:06:44.720 Windows anyhow where jerky animations by the way were a non-issue until i fired 00:06:41.280 --> 00:06:46.960 up some games i tried the game at 4k to 00:06:44.720 --> 00:06:51.199 at least get some of what i paid for out of the machine but outside of casual 00:06:49.120 --> 00:06:56.160 games like league of legends dota 2 and team fortress 2 which by the way ran 00:06:53.039 --> 00:06:59.520 fine i suspect most people will end up 00:06:56.160 --> 00:07:01.039 turning the system down to 1440p or even 00:06:59.520 --> 00:07:06.160 1080p the good news is that if you want to 00:07:03.840 --> 00:07:11.440 game on the imac some fairly demanding games can be run if you're okay with 00:07:09.039 --> 00:07:17.280 reducing your resolution crysis 3 on medium details hovered around the 50 to 00:07:14.080 --> 00:07:19.360 60 FPS range with 2x msaa and while it 00:07:17.280 --> 00:07:24.000 was pretty weird for lack of a better word sitting there gaming on an imac 00:07:21.840 --> 00:07:29.440 it's got more horses than i think a lot of people give it credit for which isn't 00:07:26.240 --> 00:07:31.680 to say that the r9 m295x was in my mind 00:07:29.440 --> 00:07:37.039 the best choice for this machine while it unfortunately wasn't quite released 00:07:33.759 --> 00:07:40.960 when this system launched i'd love to 00:07:37.039 --> 00:07:43.680 see the 5k imac updated with a gtx 980m 00:07:40.960 --> 00:07:48.720 option instead in our 1080p benchmarks the 980m which is based on the same gm 00:07:46.160 --> 00:07:55.440 204 maxwell core as NVIDIA's desktop flagship gtx 980 absolutely crushes 00:07:52.560 --> 00:08:00.879 AMD's top-tier mobile GPU in spite of the fact that i ran my benchmarks for 00:07:57.680 --> 00:08:03.599 the 980m on an MSI gt80 titan laptop 00:08:00.879 --> 00:08:09.440 whose core i7 mobile processor was running about 10 slower than the imax 00:08:06.000 --> 00:08:11.199 throttled 4970k in games 00:08:09.440 --> 00:08:14.879 so i think that's it i'm done with the imac for good now it was fun while it 00:08:13.520 --> 00:08:17.919 lasted i think i've had all the experiences that i care to have with it 00:08:16.639 --> 00:08:22.560 guys i hope you've had all the experiences you care to have with it because this is it like this video if 00:08:21.039 --> 00:08:27.680 you liked it dislike it if you disliked it leave a comment if you hate multi-part episodes 00:08:26.400 --> 00:08:31.680 and as always there's a link in the video description if you want to support us you can buy a cool t-shirt like this 00:08:30.160 --> 00:08:35.039 one give us a monthly contribution or change your bookmark for amazon to one 00:08:33.760 --> 00:08:39.200 with our affiliate code so every time you buy an imac or a dry erase marker or 00:08:37.839 --> 00:08:44.080 whatever else it is you buy on amazon we get a small kickback that kind of thing helps us out a lot thanks again for 00:08:42.000 --> 00:08:49.489 watching and as always don't forget to subscribe 00:08:54.800 --> 00:08:56.880 you
