WEBVTT 00:00:00.719 --> 00:00:06.960 Today on my video blog, we're going to be demystifying the new Intel 00:00:04.560 --> 00:00:11.120 Sandybridge processors and the chipsets that go with them a little bit, or at 00:00:08.960 --> 00:00:14.960 least we're going to be attempting to do so. Now, there's a few new features on 00:00:13.519 --> 00:00:20.160 these chips, or a few important features, let's say. So, let's start 00:00:17.119 --> 00:00:22.560 with Intel Turbo. So turbo, as we're 00:00:20.160 --> 00:00:26.720 familiar with already from the Core i7 original processor, allows the chip to 00:00:25.039 --> 00:00:32.399 overclock itself if you have enough cooling and you're not uh overstepping 00:00:29.199 --> 00:00:35.360 the thermal design power. So turbo 00:00:32.399 --> 00:00:40.079 processors such as the Core i5 2400 are allowed to turbo themselves up up to 00:00:37.360 --> 00:00:45.280 four speed grades above their stock frequency if you're using only one core. 00:00:42.480 --> 00:00:51.039 They also Okay, so here let's uh let's let's start sort of working our way 00:00:47.520 --> 00:00:56.239 along here. So they are also allowed to 00:00:51.039 --> 00:00:59.280 turn up the multiplier and OC up to four 00:00:56.239 --> 00:01:01.520 speed bins above that four speed bins. 00:00:59.280 --> 00:01:08.799 So up to eight speed bins 00:01:05.280 --> 00:01:11.680 or multiplier levels on the P67 chipset. 00:01:08.799 --> 00:01:18.799 This is also the same as over here. Okay. On the H67, it can only use turbo 00:01:16.799 --> 00:01:24.720 mode. That's it. No additional overclocking. So, four speed bins, 00:01:23.119 --> 00:01:29.200 turbo there. So, that is a regular turbo 00:01:26.880 --> 00:01:35.040 processor. Then there are completely non-turbo processors. In terms of 00:01:31.360 --> 00:01:39.040 overclocking, we have no support on H67, 00:01:35.040 --> 00:01:42.000 no support on P67, and no support on 00:01:39.040 --> 00:01:46.240 Z68. Nothing. You can overclock probably about 5% if you turn up the base clock, 00:01:44.560 --> 00:01:50.560 but it's really not recommended because you can do all kinds of nasty stuff like 00:01:48.240 --> 00:01:54.880 corrupt your hard drive and just don't do it. Okay, so then we've got unlock. 00:01:52.880 --> 00:02:00.159 So yeah, example would be like a low-end Core i3. All right, unlocked. So these 00:01:58.079 --> 00:02:04.320 ones have turbo because all the unlocked chips are already reasonably high-end 00:02:01.840 --> 00:02:09.920 chips and they also have a suffix K. So the example we're using is the Core i7 00:02:06.320 --> 00:02:12.319 2600 K. All right. So, you cannot 00:02:09.920 --> 00:02:17.200 increase Oh, well, okay. I guess you got support 00:02:13.840 --> 00:02:21.760 for the four-speed regular turbo. 00:02:17.200 --> 00:02:23.360 Okay. You have completely up to whatever 00:02:21.760 --> 00:02:30.560 the heck you want in terms of overclocking on P67, and you have up to 00:02:27.440 --> 00:02:32.239 whatever you want on Z68, which isn't 00:02:30.560 --> 00:02:36.160 out yet. So, these guys, you can overclock as much as you could possibly 00:02:34.480 --> 00:02:43.360 want. Well, until the chip reaches its limit. 00:02:38.720 --> 00:02:45.599 So, okay. Right. So, if Z68 is exactly 00:02:43.360 --> 00:02:49.200 the same as P67, then what's going on here? So, let's 00:02:47.760 --> 00:02:54.319 talk about the other important feature of these new Core i processors, and that 00:02:51.920 --> 00:02:57.680 is their onboard graphics. So, there are a few different kinds of onboard 00:02:55.760 --> 00:03:01.680 graphics built into these chips. The K series chips actually have the highest 00:02:59.360 --> 00:03:10.080 end onboard graphics, which is pretty funny because uh no 00:03:05.599 --> 00:03:11.360 onboard graphics on P67. So on the 00:03:10.080 --> 00:03:17.200 platform where you can actually overclock these K series chips, you have 00:03:13.840 --> 00:03:20.720 no support for onboard video. Uh here we 00:03:17.200 --> 00:03:22.560 have onboard video enabled, but we 00:03:20.720 --> 00:03:26.879 actually can overclock the chip. So you have the best possible graphics core on 00:03:25.040 --> 00:03:30.799 the one that is only supported on the one where you can't overclock it and it 00:03:28.319 --> 00:03:36.879 has the overclock. So here we have onboard graphics enabled. That is the 00:03:33.519 --> 00:03:39.040 difference between Z68 and P67. It has 00:03:36.879 --> 00:03:43.760 sort of the best of both worlds, but it isn't out yet. So these ones don't have 00:03:41.440 --> 00:03:48.720 quite as powerful an onboard graphics card. So same thing here. No onboard 00:03:46.640 --> 00:03:52.640 graphics supported. Here it's supported. Here it's supported. And same thing 00:03:50.400 --> 00:03:58.159 here. These ones have the lowest end onboard graphics and here is no and here 00:03:55.599 --> 00:04:02.480 is okay. So that is the difference between all these different chips and 00:04:00.080 --> 00:04:07.200 all these different chipsets. So in summary, if you are not using onboard 00:04:04.879 --> 00:04:13.599 graphics and you are overclocking, then your choice is going to be a K series 00:04:09.599 --> 00:04:16.320 processor and a P67 motherboard. If you 00:04:13.599 --> 00:04:20.720 want to use onboard graphics and you don't really care quite as much about 00:04:18.000 --> 00:04:25.520 performance, you do not need a K series processor, you can get either one of 00:04:22.560 --> 00:04:30.639 these and an H67 motherboard. If you want the best of both worlds, I guess 00:04:27.280 --> 00:04:33.680 you'll just have to wait until Z68 00:04:30.639 --> 00:04:35.440 launches at some point in the future. 00:04:33.680 --> 00:04:39.600 Don't forget to subscribe to Linus Tech Tips for more unboxings, reviews, and 00:04:37.919 --> 00:04:42.600 other videos about computers and whatnot.
