so in my XFX uh 5850 unboxing what I
0:03
realized is that I didn't really go into enough depth about what are the
0:07
differences between these two cards so first let's talk about the physical
0:10
differences okay the most obvious one is the difference in length so we're going
0:14
to measure the 5870 from the very edge of the PCI
0:20
bracket here to the end of the cart is 11 oh it's like 11 and 1/8 of an inch
0:26
and then for the 5850 the same measurement is only N9 and a oh just a
0:32
hair over a half so it's about 9 and you know 5/8 of an inch okay but something
0:38
that you have to factor in is that you're going to need almost another inch
0:42
or so maybe 3/4 of an inch for the PCI
0:45
Express connector so it actually is more like more like 10 and 1 half so you're
0:50
only looking at about a 1 in difference between these two cards when they're
0:53
installed in your case now they both support direct X11 and they both support
0:57
ifinity with up to three monitors One DisplayPort and two other digital
1:02
displays now in terms of the overall spec I'm going to cheat a little bit
1:06
here and I'm going to look at the chart on Hardware conu because it's very very
1:09
useful so the 5870 is clocked at 850 MHz
1:13
on the GPU core and the 5850 is clocked at 725 the 5870 has faster memory at 4.8
1:21
GHz whereas the 5850 is clocked at 4,000
1:24
so just 4 GHz there are a couple other
1:27
differences for example the Stream processors are down from 1600 stream
1:32
processors to 1440 and then you're also
1:35
a little bit reduced on the rops okay or sorry the texture units the
1:41
RS are the same so what that means is
1:44
that with the 5850 based on all the benchmarks I've seen I haven't had a
1:48
chance to test it yet you're looking at about 10 to 15% slower but at a
1:52
significant cost reduction so thank you for checking out my differences between
1:57
the 5870 and the 5850 video
