r9 360, does not need extra power from psu... Could this mean efficiency

[marldorthegreat]

 

 

This image shows the r9 300 series oem cards, the r9 380 does not require any additional connectors, comared with the r9 260s 1 x 6pin connector. And the 380 only needs 2x6 pin connectors, wheras the the 280 used a 6 pin and 8pin connector.

 

Could this mean less power draw????

[ind3x]

yes, but this is still a rumor.

iirc a card can draw 75W from the pcie.

[marldorthegreat]

This is from the AMD website. This is real

[TheSLSAMG]

Those are OEM cards. The R9 380 is an R9 285 in this pic, as the R9 370 is an R7 265 and the R9 360 is an R7 260.

Yes but if you read it. the 360 does not need additional power, but the 260 did. 

[Sintezza]

6 pin is 75W

8 pin is 150W

pci-e slot power is 75W.

 

So you can do the math.

[marldorthegreat]

6 pin is 75W

8 pin is 150W

pci-e slot power is 75W.

 

So you can do the math.

r9 360 tdp <75 watt

r9 370 tdp <150 watt

r9 380 tdp < 225 watts

[TheSLSAMG]

They likely downclocked the card. OEM cards are generally gimped and tweaked in one way or another, so that's probably how they gimped it. The PCI-E slot can provide 75W of power. The R7 260's TDP is 95W. Downclock it a little and lower the core voltage and 75W should be easy. TDP isn't necessarily power consumption, but they provide a roundabout figure for it.

TDP isn't a power consumption measure you know that ?

"Watts" is power. 

[cesrai]

"Watts" is power.

The thermal design power (TDP), sometimes called thermal design point, is the maximum amount of heat generated by the CPU that the cooling system in a computer is required to dissipate in typical operation. Rather than specifying CPU's real power dissipation, TDP serves as the nominal value for designing CPU cooling systems.

So they are just abandoning hte R7 nomenclature alltogether? Why do they keep using the R9 then?

[Sintezza]

TDP, stands for thermal design power, aka Heat output.

Its a number measured in Watts on which your cooling solution must be capable to dissipate from the die..

[Sky Daddy]

also needs a crossfire connector, this is undoubtedly a rebrand

[Megahurt]

It's the expected power consumption at stock, so kind of.

[GoldSrc]

Nope, TDP =/= electric power consumption.

TDP is related to heat dissipation.

A 3570K with its 77W TPD can use +100W of power on full load, on idle is close to 50W.

A 3570K with its 77W TPD can use +100W of power on full load, on idle is close to 50W.

In electronics, I'd be willing to bet that  more than 99% of the energy gets converted into heat. There is no physical work being done so the only possible way it gets converted is heat. Also I call bullshit on that 100W with the 3570k, and MAJOR bullshit on the 50W at idle.

[Aniallation]

They knocked off a PCIe power connector on the 270 compared to it's rebrand of the 7870, which had two.

This. TDP is called Thermal power design for a reason. Too many people think TDP = power consumption, although it may be close for many components, they are not the same thing.

If that were the case, power supplies would never have 80+% efficiency.

Electronics are more efficient than they were years ago, an 80% efficient PSU turns 20% into heat not 99%.

 

And you're wrong, the 3570K uses around 50W at idle and +100W at full load.

3570K load

3570K idle

 

And since most PCs don't use more than 450-500W on full load, those numbers are consistent.

But hey, you're free to do your own test if you don't trust Anandtech ones.

It does not necessarily equate to electricity. It can, but not all the time.

I think you are majorly misinformed.

Wow that was painful to read. With 80% efficiency PSUs, 20 % of the power is indeed being turned into heat, inside the psu, the remaining 80% is being turned into heat in the components that it powers. You do realise that those graphs show system power consumption, motherboards, hard drives, gpus, etc. don't run on pixie dust, they use power. The tdp of the processor, is for the processor alone, and the VRMs have an efficiency rating too, like power supplies.

"Total system power consumption" includes CPU, chip set(Z77), ram, SSD/HDD, etc. You can't say i7 3770K uses ~50W when idling, because you don't know the power consumption of other components.
