Do all the ATI 4670's Brands use the same amount of power?

Do all the ATI 4670's brands use the same amount of power? Because everyone has been telling me to get a 4670 because it will work with a Dell 305 Watt Power Supply and a PCI x16 slot. I just wanted to make sure that all the brands use the same power. Because if they do not use the same power, I do not want to pick out the wrong one. I was thinking of the

SAPPHIRE 100256L Radeon HD 4670 1GB 128-bit GDDR3 PCI Express 2.0 x16 HDCP because of the extra RAM it has over the other cards.

Or the

Apollo AP-HD4670 256MB Radeon HD 4670 256MB 128-bit GDDR4 PCI Express 2.0 x16 HDCP because of the GDDR4.

But you guys know better so you tell me. Do not worry about the price for the 4670 I do not mind spending an extra 20 dollars if it is worth it. I mainly play WoW and want to play maxed out if I can.

More about 4670 brands amount power
  1. I'd go with the first one, but the HD 4670 really doesn't need more than 512Mb of memory. I'd just grab the 512Mb one that has the fastest memory.

    But they all take the same amount of power, at least within a few watts.
  2. I think they are the same .
  3. I'm pretty sure that according to the release material, the 1GB model uses the same power as the 512MB version (59W). The difference however is that the 1GB version has 900MHz (vs 1GHz on the 512MB version) memory bus. Link. This was probably required to keep the additional memory in the same power envelope. 1GB models that ship with 1GHz memory probably use a few watts more. I haven't been able to find any useful info on the 256MB GDDR4 model, but I'd avoid it because in this day and age it really is too little framebuffer. My 512MB version serves me well. Although I haven't seen any benchmarks, I don't think that the 1GB model will perform much better since the memory is so (relatively) slow. If they offered a 1GB GDDR4 version I'd say go for it (they don't).

  4. All HD 4670 video cards should use the same mount of of power as long as the spec are the same.

    Thus a HD 4670 with 1GB of RAM will consume a little more power than the 512MB RASM version.

    Also an overclocked HD 4670 will use more power than a standard clocked HD 4670.
