So I am looking to upgrade from my sapphire 4670 ddr3 1gb and I wanted to know which one would be the best upgrade between the 6670 1gb DDR3 and the 7750 1gb gddr5 and the 4870 1gb gddr5.which of these cards is the best for gaming?Also my cpu is the phenom 965 @ 3.4ghz with a 800w power supply if that helps with anything.

More about : 4870 7750 6670

If you have a 4870 then the cards would be a downgrade... Could you spend the extra $$ to get a 7770?

well I currently have a sapphire 4670 ddr3 1gb.So is the 4870 the best out of all them?and I will look into that card,I am on a really tight budget for a graphics card.

I'd go for the 7750. It has about the same raw performance as a 4870 and it has directx11, which might become important going forward. The 6670 has similar performance to a 4670.

Alright thank you guys so much for the replies.I will most likely get a 7750 or a 4870.Is there a huge difference between the cards in performance?I might be doing some overclocking on the card so which one would I get a better result with?

1ST 4870 VS 6670


The Radeon HD 4870 1GB has core clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.
Compare all of that to the Radeon HD 6770 1GB, which comes with a clock speed of 900 MHz and a GDDR5 memory speed of 1050 MHz. It also features a 128-bit memory bus, and uses a 40 nm design. It is made up of 800 SPUs, 40 Texture Address Units, and 16 ROPs.


Power Consumption (Max TDP)

Radeon HD 6770 1GB 108 Watts
Radeon HD 4870 1GB 150 Watts
Difference: 42 Watts (39%)

Memory Bandwidth

the Radeon HD 4870 1GB should perform much faster than the Radeon HD 6770 1GB in general.

Texel Rate

The Radeon HD 6770 1GB is a little bit (approximately 20%) more effective at texture filtering than the Radeon HD 4870 1GB. but in real time i will not see any performance difference

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6770 1GB is a better choice, but it probably won't make a huge difference


BETWEEN THEM I THINK THE 6670 WILL BE BETTER FOR YOU


NOW THE 7750 VS 4870 -

The Radeon HD 4870 1GB has clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 RAM. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 ROPs.
Compare all that to the Radeon HD 7750, which features core clock speeds of 800 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Consumption (Max TDP)

Radeon HD 7750 55 Watts
Radeon HD 4870 1GB 150 Watts
Difference: 95 Watts (173%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 4870 1GB will be 60% quicker than the Radeon HD 7750 overall, due to its greater bandwidth.

Texel Rate

The Radeon HD 4870 1GB is a small bit (approximately 17%) better at AF than the Radeon HD 7750.



Pixel Rate

If using a high resolution is important to you, then the Radeon HD 7750 is a better choice, though only just barely..


AGAIN 4870 WON THE MATCH.



SO, I THINK BETWEEN 4870 , 6670 AND 7750. THE 4870 IS ALWAYS A GREATER CHOICE.

id say the 7750 just to have the DX11 capabilities on some games.

Comparing specs like that only really works when comparing GPUs of the same generation and architecture. A shader on a 7000 series card will perform differently at a given clockspeed than a shader on a 4000 series card, etc.

I would say go for the 7750 if those are your only choices, it is more power efficient and runs a lot cooler than the 4870, and you get DirectX 11 support, which might become more important if game developers start to follow Crytek's lead and drop DirectX 9 and 10 support in future games.

Yea dont listen to KAIJER, he seems to be lost in some odd world were hardware doesn't get outdated.

So it looks like the 4870 isn't that bad after all.But getting the 7750 will keep me from spending more money on a upgrade for a while but I will most likely play games from last year and not really the new ones(besides gta 5!).I mean will the 4870 even be that good overclocked?what can i expect to get with the 4870 overclocked and a phenom 965 @ 3.4ghz with 8gb of ram.

the 7750 will overclock better because it has much better cooling with it being on a 28nm fab. The 4870 is on 65nm I think, not 100%, but it basically uses more power, creates much much much much more heat (20C difference). Also im not sure were you are finding new 4870.

Well the cooler the graphics card the better.I will be saving up for a 7750(or maybe a 7770 for a few more bucks)Maybe I can get lucky and win a auction on ebay for a cheap one.And I was going to be bidding on ebay for the 4870.
