00:00:00,719 --> 00:00:06,960
Today on my video blog, we're going to be demystifying the new Intel

2
00:00:04,560 --> 00:00:11,120
Sandybridge processors and the chipsets that go with them a little bit, or at

3
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

4
00:00:13,519 --> 00:00:20,160
these chips, or a few important features, let's say. So, let's start

5
00:00:17,119 --> 00:00:22,560
with Intel Turbo. So turbo, as we're

6
00:00:20,160 --> 00:00:26,720
familiar with already from the Core i7 original processor, allows the chip to

7
00:00:25,039 --> 00:00:32,399
overclock itself if you have enough cooling and you're not uh overstepping

8
00:00:29,199 --> 00:00:35,360
the thermal design power. So turbo

9
00:00:32,399 --> 00:00:40,079
processors such as the Core i5 2400 are allowed to turbo themselves up up to

10
00:00:37,360 --> 00:00:45,280
four speed grades above their stock frequency if you're using only one core.

11
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

12
00:00:47,520 --> 00:00:56,239
along here. So they are also allowed to

13
00:00:51,039 --> 00:00:59,280
turn up the multiplier and OC up to four

14
00:00:56,239 --> 00:01:01,520
speed bins above that four speed bins.

15
00:00:59,280 --> 00:01:08,799
So up to eight speed bins

16
00:01:05,280 --> 00:01:11,680
or multiplier levels on the P67 chipset.

17
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

18
00:01:16,799 --> 00:01:24,720
mode. That's it. No additional overclocking. So, four speed bins,

19
00:01:23,119 --> 00:01:29,200
turbo there. So, that is a regular turbo

20
00:01:26,880 --> 00:01:35,040
processor. Then there are completely non-turbo processors. In terms of

21
00:01:31,360 --> 00:01:39,040
overclocking, we have no support on H67,

22
00:01:35,040 --> 00:01:42,000
no support on P67, and no support on

23
00:01:39,040 --> 00:01:46,240
Z68. Nothing. You can overclock probably about 5% if you turn up the base clock,

24
00:01:44,560 --> 00:01:50,560
but it's really not recommended because you can do all kinds of nasty stuff like

25
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.

26
00:01:52,880 --> 00:02:00,159
So yeah, example would be like a low-end Core i3. All right, unlocked. So these

27
00:01:58,079 --> 00:02:04,320
ones have turbo because all the unlocked chips are already reasonably high-end

28
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

29
00:02:06,320 --> 00:02:12,319
2600 K. All right. So, you cannot

30
00:02:09,920 --> 00:02:17,200
increase Oh, well, okay. I guess you got support

31
00:02:13,840 --> 00:02:21,760
for the four-speed regular turbo.

32
00:02:17,200 --> 00:02:23,360
Okay. You have completely up to whatever

33
00:02:21,760 --> 00:02:30,560
the heck you want in terms of overclocking on P67, and you have up to

34
00:02:27,440 --> 00:02:32,239
whatever you want on Z68, which isn't

35
00:02:30,560 --> 00:02:36,160
out yet. So, these guys, you can overclock as much as you could possibly

36
00:02:34,480 --> 00:02:43,360
want. Well, until the chip reaches its limit.

37
00:02:38,720 --> 00:02:45,599
So, okay. Right. So, if Z68 is exactly

38
00:02:43,360 --> 00:02:49,200
the same as P67, then what's going on here? So, let's

39
00:02:47,760 --> 00:02:54,319
talk about the other important feature of these new Core i processors, and that

40
00:02:51,920 --> 00:02:57,680
is their onboard graphics. So, there are a few different kinds of onboard

41
00:02:55,760 --> 00:03:01,680
graphics built into these chips. The K series chips actually have the highest

42
00:02:59,360 --> 00:03:10,080
end onboard graphics, which is pretty funny because uh no

43
00:03:05,599 --> 00:03:11,360
onboard graphics on P67. So on the

44
00:03:10,080 --> 00:03:17,200
platform where you can actually overclock these K series chips, you have

45
00:03:13,840 --> 00:03:20,720
no support for onboard video. Uh here we

46
00:03:17,200 --> 00:03:22,560
have onboard video enabled, but we

47
00:03:20,720 --> 00:03:26,879
actually can overclock the chip. So you have the best possible graphics core on

48
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

49
00:03:28,319 --> 00:03:36,879
has the overclock. So here we have onboard graphics enabled. That is the

50
00:03:33,519 --> 00:03:39,040
difference between Z68 and P67. It has

51
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

52
00:03:41,440 --> 00:03:48,720
quite as powerful an onboard graphics card. So same thing here. No onboard

53
00:03:46,640 --> 00:03:52,640
graphics supported. Here it's supported. Here it's supported. And same thing

54
00:03:50,400 --> 00:03:58,159
here. These ones have the lowest end onboard graphics and here is no and here

55
00:03:55,599 --> 00:04:02,480
is okay. So that is the difference between all these different chips and

56
00:04:00,080 --> 00:04:07,200
all these different chipsets. So in summary, if you are not using onboard

57
00:04:04,879 --> 00:04:13,599
graphics and you are overclocking, then your choice is going to be a K series

58
00:04:09,599 --> 00:04:16,320
processor and a P67 motherboard. If you

59
00:04:13,599 --> 00:04:20,720
want to use onboard graphics and you don't really care quite as much about

60
00:04:18,000 --> 00:04:25,520
performance, you do not need a K series processor, you can get either one of

61
00:04:22,560 --> 00:04:30,639
these and an H67 motherboard. If you want the best of both worlds, I guess

62
00:04:27,280 --> 00:04:33,680
you'll just have to wait until Z68

63
00:04:30,639 --> 00:04:35,440
launches at some point in the future.
