Practice English Speaking&Listening with: Sapphire Radeon HD 4850 X2 PCIe Video Card

Difficulty: 0

Alright, you're looking at a sweet new card.

It's probably going to be one of the biggest cards that's going to come out for a while.

It's probably the biggest one since the 4870 X2 or maybe the 4870.

You're looking at the 4850 X2.

And you guys know that the 4850 is a great bang for the buck.

It's an awesome card. It plays all the games. It's very affordable.

But what if you need a litte bit more for performance?

Now it's in an X2 form Factor. You get two of everything.

Twice the screen processors, twice the GPUs, twice the memory,

and you even get twice the cooler, because check it out,

this thing has a non-reference design, if you notice, it has two fans on there.

And if you look inside of there, I don't know if you can see it,

Really, really cool, non-reference GPU cooler in there.

It's got coolers on this end for your VRMs and your capacitors are all right behind

there kind of touching. That keeps all that cool. You have a backplate cooler

for your voltage regulators which is very interesting.

And, another thing that's extremely interesting about this thing, oh boy, what is that?

Four DVIDs on board, which is actually kind of ludicrous.

I don't know what you're going to do with that much connectivity,

but if you are a day trader and you decide to play games at the same time,

I don't know what would happen when you'd want to use four DVIs,

you also have that TV out right there. This is a double slot solution as you can tell,

and this is a pretty impressive card. Let's talk about the specs:

625 MHz core clock, the memory's at 993 which is extremely fast,

it's over 18,000 Mhz when it's double-pumped, remember it's DDR3.

2 GiB of DDr3 in total, 1 GiB per GPU. they're not shared memory,

they're discrete for each GPU. So you have 1 GiB of frame buffer,

feeding each GPU independently, they do not access each other.

800 shaders per GPU as well, so that's 1,600 in total.

that's a lot of shading power. Those are also at 625 MHz.

You also have a 256 bit interface for that memory. Let's talk about some other things.

Besides the 4 Dual DVIs, everything else is going to be the same as the 4850.

You have DirectX 10.1, you have shader model 4.1 which is a little bit new,

you have the Avivo technology for your videos, You have the UVD 2.0,

which is your unified video decoder, so you can do Blu-rays and HD DVDs.

Also, included in the box is this HDMI to DVI adapter, so with that UVD 2.0,

you will be pumping 7.1 channel lossless audio through your HDMI cable to your television

with just this. This is all you need, it's all integrated.

You also get... You have the HDMI, you can do game physics with these cards,

they did finally import physics to ATI cards. It does require some interesting power connectors,

I'm going to show them to you right here: on the top you have a 8-pin PCI express connector

and a 6-pin PCI express connector. It does ask for 650 watts,

I ran it on a 500 watt Corsair and it ran, no problem.

But, if you have a lower end power supply it might be safer than sorry

to go with the 650 minimum. I't didn't have an amperage specification,

but I'm sure that if you have a 650 watt power supply, you will have plenty of amps

to run on there. It is ready for Crossfire X. The bridge is in the typical location

which is... right there. And you do get a Crossfire bridge in the box.

So it's not going to be hard to suit these up. And another one.

You can Crossfire them with a 4870, You can Crossfire them with a 4850,

with another 4850 X2 or with a 4870 X2. It's really up to you.

Anything in the 4800 family - it's going to Crossfire, no problem.

Also included in the box is a DVI to VGA adapter in case you have a D-sub.

And a composite adapter, in case you have an old TV and just run your videos

to an old television. you also get this helpful little device:

This is a 4-pin Molex to 6-pin PCI express connector. So if you don't have the older

PCI express connectors, this will let you use them and even if you don't have the 8-pin,

you can still use it because this one comes with a 8-pin as well. That one takes 2 Molexes.

So even if you have the oldest power supply that has no PCI express,

you can still run this video card, assuming that you have the correct amount of power.

Also included in the box is this break-away cable, and this breaks away

from a 7 pin digital S-Video cable to components. And this will do 1080i to your HDTV

if you do not have a HDMI cable but you do have these lying around.

You also get a pretty good manual, with a lot of interesting information on it.

And you get your AMD Ruby Rom disc with wallpapers and some games

and some simple stuff. 3DMark Vantage included in the box,

with the license key that works. this is amazing. This is going to let you know

hey, what kind of performance upgrades did I get by switching to this video card?

Was it worth for nothing? Absolutely not. it's going to give you a precise number,

It's a synthetic benchmark and it does test your graphics. It's designed for DirectX 10.1

and 10, so it is going to test all the latest and greatest features of your video card

and its drivers. You also get a driver disc, which on board has the ATI Catalyst control panel

lets you overclock your video cards, run it to TVs, run multiple monitors,

do a bunch of stuff with this disc. you also get a couple of extra things:

these are power suite and DVD suite which come it, and you'll be using these to burn CDs,

DVDs and music, games, videos, whatever you want. You can use those, all in the box.

let's get to some benchmarks. Now, looking at Crysis, Crysis Warhead, FarCry 2

and Call of Duty: World at War, this is on a QX90770 at 3.8GHz,

4GiB of 1,600 MHz DDR3, and one 4850 X2, we also compared a GTX 280

and a 4870 X2 just to give you that general idea of that high end of cards.

I'll tell you what - this card did beat the GTX280 in every single test that I ran it on.

So let's jump into those benchmarks. These are all 1920X1200,

pretty much your 24-inch standard resolution looking at Crysis on high settings

with 0 anti-aliasing. The 4850 X2 to 51, which is extremely impressive

when you realize that the GTX 280 only did 44, and the 4870 X2 only did 4 more at 55.

So that's ridiculous. At Crysis Warhead we increased the settings,

this is the enthusiast settings with 0 anti-aliasing. you see the frame rate-

35 for the 4850 X2 and only 37 for the 4870 X2 so 2 fames is almost nothing.

And when you compare it to the GTX 280 at only 29 frames per second

that's a huge increase in performance for a card that is just a little bit more expensive,

and definitely is going to be much more viable for a lot of gamers that are not super rich

with very deep pockets. Moving on to FarCry 2,

these are on the ultra settings, 4 times anti-aliasing,

you're going to see 62 FPS on that 4850 X2, which is really impressive.

Only 2 more for the 4870, and the GTX 280 only got 54,

so you're seeing some really impressive benchmarks as far as FarCry 2 goes.

And finally Call of Duty, World at War, absolutely ridiculous, 125 FPS for the 4850 X2,

up to 140 on the 4870 X2 and we still got 120 on the GTX 280.

there seems to be a smaller gap between them all. So again, the 4850,

first of all looks ridiculously cool. Extremely sharp, it's all metal on the top,

anodized black aluminum on the top looks really sharp, very aggressive design.

It's got 4 DVI ports, it's ready for Crossfire, it's got shader model 4.1 and DirectX 10.1.

625 MHz core clock, and that's 2 cores that are on there, because you've got 2 GPUs,

2 1GiB frame buffers feeding each GPU at 800 shaders per GPU for a total of 1,600 ALUs.

Absolutely out of control, and the price is perfect,

make sure you have enough power, and another thing - this thing run extremely cool

compared to the 4870s, no more of that 90c degree stuff, these run a lot cooler.

As a matter of fact, I measure the temperature, I just don't know if I wrote it down.

I did measure the temperature but they run in the 60c degree on full load

and in the 40s on no load. So an excellent card,

if you have any questions on it, Email me, and I'll see you guys next time.
