1 00:00:00,240 --> 00:00:06,960 now i had originally intended to do using the imac with Windows and a 2 00:00:04,880 --> 00:00:13,120 top-tier mobile graphics card performance showdown with the Radeon r9 3 00:00:09,480 --> 00:00:15,040 m295x 8 gig yes actually 8 gig versus 4 00:00:13,120 --> 00:00:20,400 NVIDIA's king of the hill gtx 980m mobile as separate videos but my wife 5 00:00:18,400 --> 00:00:23,600 and the rest of the internet complains that we've been doing too many 6 00:00:21,520 --> 00:00:28,400 multi-part episodes so here they are together you won this battle but not the 7 00:00:26,320 --> 00:00:31,840 teaser battle my gs30 stealth external graphics card notebook review is coming 8 00:00:29,760 --> 00:00:31,840 soon 9 00:00:37,920 --> 00:00:45,120 experience silent performance with the new cooler master silencio 652s 10 00:00:42,480 --> 00:00:48,320 minimalist design maximum compatibility click now to learn more 11 00:00:48,719 --> 00:00:54,559 so bootcamp is freaking awesome you just 12 00:00:52,079 --> 00:00:59,199 spotlight search bootcamp assistant pop in a usb thumb drive point it at an iso 13 00:00:57,360 --> 00:01:04,960 then it walks you through resizing your os 10 partition creating a Windows one 14 00:01:01,440 --> 00:01:07,840 and then without any preboot f8 nonsense 15 00:01:04,960 --> 00:01:11,520 it runs the setup process all the while restarting automatically into the 16 00:01:09,439 --> 00:01:14,960 correct thing then finally you land on the Windows desktop you're prompted to 17 00:01:13,040 --> 00:01:20,479 install all the necessary drivers from one executable it reboots again and boom 18 00:01:17,759 --> 00:01:24,560 you are ready to rock the experience is so seamless compared to when i've dual 19 00:01:22,479 --> 00:01:27,759 booted in the past although admittedly it's been a while i have so many drives 20 00:01:26,479 --> 00:01:31,280 that i rarely see the point in partitioning for multiple os's accepting 21 00:01:29,680 --> 00:01:35,200 cases where the extremely limited upgradability 22 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 23 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 24 00:01:41,920 --> 00:01:50,399 know what they were expecting macs are not made of dragon scales and the force 25 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 26 00:01:52,479 --> 00:01:59,920 specs as that mac i cannot stress this enough there is nothing about a knack 27 00:01:57,840 --> 00:02:05,040 that makes it special other than subjectively beautiful industrial design 28 00:02:02,560 --> 00:02:10,000 driver validation and component quality control are arguably important things 29 00:02:07,119 --> 00:02:14,319 but they don't affect performance oh and i guess there's a little bootcamp doodad 30 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 31 00:02:16,879 --> 00:02:24,080 astute among you may have noticed that asterisk on the exactly about 40 seconds 32 00:02:21,840 --> 00:02:28,720 ago what was that thrown in there for well a couple of reasons first and 33 00:02:26,400 --> 00:02:34,319 foremost is that for anything to perform exactly the same it has to not be 34 00:02:31,440 --> 00:02:38,720 hamstrung on a normal pc with a separate tower and monitor a 4970k 35 00:02:36,800 --> 00:02:43,040 will typically operate at anywhere from four gigahertz to 4.4 gigahertz 36 00:02:41,040 --> 00:02:47,120 depending on how multi-threaded a workload you're throwing at it thanks to 37 00:02:45,360 --> 00:02:53,680 turbo boost which you can learn more about here on the imac thanks to the 38 00:02:50,239 --> 00:02:57,920 quiet but not particularly powerful 39 00:02:53,680 --> 00:03:01,120 cooling system that CPU idles around 50 40 00:02:57,920 --> 00:03:04,000 degrees ramps up to 80 degrees in under 41 00:03:01,120 --> 00:03:09,120 10 seconds then in spite of the fan ramping up aggressively at 30 seconds 42 00:03:06,560 --> 00:03:16,080 begins to thermal throttle at 40 seconds hits 100 degrees at 50 seconds and stays 43 00:03:12,959 --> 00:03:18,560 there operating anywhere between 3.6 to 44 00:03:16,080 --> 00:03:23,840 4 gigahertz with a multi-threaded workload about a five to fifteen percent 45 00:03:21,680 --> 00:03:29,680 reduction in the performance that CPU could achieve in something like you know 46 00:03:26,720 --> 00:03:34,720 uh multi-core video rendering if it had a better cooler it really raises the 47 00:03:32,319 --> 00:03:39,120 question why did apple bother to give users the option of a top tier chip like 48 00:03:37,120 --> 00:03:42,400 this when it was never going to reach its rated speeds when it matters most 49 00:03:41,440 --> 00:03:47,280 anyway the other reason my asterisk was put in 50 00:03:44,879 --> 00:03:51,200 there is something that i was very very 51 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 52 00:03:53,519 --> 00:03:59,200 fewer of them are running Windows so there wasn't a ton of information about 53 00:03:57,920 --> 00:04:05,280 what i'm doing here and i had to discover for myself that thanks to 54 00:04:02,480 --> 00:04:09,599 some combination of AMD's driver AMD's hardware and apple's custom timing 55 00:04:07,920 --> 00:04:16,959 controller that enabled them to deliver a 5k single tile display in Windows you 56 00:04:13,040 --> 00:04:19,680 will be limited to 4k resolution max so 57 00:04:16,959 --> 00:04:25,120 that's 3840x2160 on your 5120 by 2880 display something 58 00:04:23,280 --> 00:04:28,639 that doesn't seem to be bothering this fella in the apple community discussion 59 00:04:27,280 --> 00:04:33,120 thread where folks are saying they've been bounced around between apple and 60 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 61 00:04:35,120 --> 00:04:40,960 it but it bothers me a lot 62 00:04:38,720 --> 00:04:45,479 thanks to the much higher resolution than normal and much higher pixel 63 00:04:42,720 --> 00:04:49,440 density than normal of this display the approximations that come along with any 64 00:04:47,600 --> 00:04:53,759 non-native resolution operation of a monitor and lcd monitor be specific can 65 00:04:52,000 --> 00:04:58,560 be more accurate than they otherwise would be but there is still 66 00:04:56,000 --> 00:05:02,720 discoloration and blurriness on text that makes everything look a little 67 00:04:59,919 --> 00:05:07,199 fuzzy what a disappointment so the only real new information i have 68 00:05:05,120 --> 00:05:11,919 since my previous videos on the 27-inch retina 5k imac is that it thermal 69 00:05:09,600 --> 00:05:17,520 throttles while performing CPU intensive tasks seemingly by design since apple 70 00:05:15,039 --> 00:05:24,240 avoids ramping the cooling fan up for as long as it can before finally giving in 71 00:05:20,800 --> 00:05:27,120 and cooling that poor CPU and it cannot 72 00:05:24,240 --> 00:05:31,280 run its display at 5k in a native Windows environment which coupled with 73 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 74 00:05:33,919 --> 00:05:40,880 makes this machine optimal for very specific people so with that mini 75 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 76 00:05:42,479 --> 00:05:48,960 performance of the r9 m295x versus 77 00:05:45,600 --> 00:05:50,720 NVIDIA's gtx 980m first a bit about the 78 00:05:48,960 --> 00:05:56,479 m295x a GPU that has only shown up in this 79 00:05:53,919 --> 00:05:59,680 imac in its top tier configuration so far to my knowledge although i'm sure 80 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 81 00:06:01,600 --> 00:06:07,600 tonga architecture as a desktop r9285 82 00:06:04,960 --> 00:06:13,199 but with 14 more stream processors and texture units and an 8 reduction in core 83 00:06:10,560 --> 00:06:18,880 clock with the same 256 bit memory bus but in the case of this computer anyway 84 00:06:15,520 --> 00:06:21,280 it features a massive 8 gig frame buffer 85 00:06:18,880 --> 00:06:25,039 versus the 2gig one on its closest desktop equivalent presumably because 86 00:06:23,360 --> 00:06:30,560 apple felt it needed it to drive the retina imax 5k display not that it kept 87 00:06:27,919 --> 00:06:34,080 os 10 yosemite from frequently stuttering while switching desktops are 88 00:06:32,160 --> 00:06:38,720 using mission control anyway but today's video was not about running the imac in 89 00:06:36,080 --> 00:06:44,720 Windows anyhow where jerky animations by the way were a non-issue until i fired 90 00:06:41,280 --> 00:06:46,960 up some games i tried the game at 4k to 91 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 92 00:06:49,120 --> 00:06:56,160 games like league of legends dota 2 and team fortress 2 which by the way ran 93 00:06:53,039 --> 00:06:59,520 fine i suspect most people will end up 94 00:06:56,160 --> 00:07:01,039 turning the system down to 1440p or even 95 00:06:59,520 --> 00:07:06,160 1080p the good news is that if you want to 96 00:07:03,840 --> 00:07:11,440 game on the imac some fairly demanding games can be run if you're okay with 97 00:07:09,039 --> 00:07:17,280 reducing your resolution crysis 3 on medium details hovered around the 50 to 98 00:07:14,080 --> 00:07:19,360 60 FPS range with 2x msaa and while it 99 00:07:17,280 --> 00:07:24,000 was pretty weird for lack of a better word sitting there gaming on an imac 100 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 101 00:07:26,240 --> 00:07:31,680 to say that the r9 m295x was in my mind 102 00:07:29,440 --> 00:07:37,039 the best choice for this machine while it unfortunately wasn't quite released 103 00:07:33,759 --> 00:07:40,960 when this system launched i'd love to 104 00:07:37,039 --> 00:07:43,680 see the 5k imac updated with a gtx 980m 105 00:07:40,960 --> 00:07:48,720 option instead in our 1080p benchmarks the 980m which is based on the same gm 106 00:07:46,160 --> 00:07:55,440 204 maxwell core as NVIDIA's desktop flagship gtx 980 absolutely crushes 107 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 108 00:07:57,680 --> 00:08:03,599 the 980m on an MSI gt80 titan laptop 109 00:08:00,879 --> 00:08:09,440 whose core i7 mobile processor was running about 10 slower than the imax 110 00:08:06,000 --> 00:08:11,199 throttled 4970k in games 111 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 112 00:08:13,520 --> 00:08:17,919 lasted i think i've had all the experiences that i care to have with it 113 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 114 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 115 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
