ATI Radeon HD 5450 & HD 5570 Review
S.T.A.L.K.E.R.: Call of Pripyat
The events of S.T.A.L.K.E.R.: Call of Pripyat unfold shortly after the end of S.T.A.L.K.E.R.: Shadow of Chernobyl. Having discovered about the open path to the Zone center, the government decides to hold a large-scale military “Fairway” operation aimed to take the CNPP under control.
The S.T.A.L.K.E.R. (just simply called STALKER) series has made quite an impact on PC gaming with its Action-RPG, FPS hybrid style gameplay. The latest game in the series, Call of Pripyat, has a DX11 benchmark which was used to compare the performance of the two cards being featured today.
Let me begin with the results of DX10 benchmarks.
STALKER: CoP - 8500GT
STALKER: CoP - HD 5450
STALKER: CoP - HD 5570
STALKER: CoP - 9800GT
Now here are the charts for the DX11 benching runs:
STALKER: CoP - HD 5450 - DX11
STALKER: CoP - HD 5570 - DX11
The DX11 performance is admirable when comparing it to DX10. However, the actually gameplay might be hampered by slower framerates, limited only by the power of the cards.
The 5570 consumes 69 watts more power under load and 40 watts more in idle? No way, something must have gone wrong here. The results on other sites are in a different league – single digit watt difference in idle and ~30 watts under load.
Thanks for your comment Howitzer. The fact is exactly as I stated, this is the power draw on the *entire* system. Other sites may have the tools such as power meters that can measure the video card power draw at the slot level. I am only privy to a Kill-A-Watt unit.
The major factor in this is that the 1100W PSU that powers my system has driven up the idle power load quite a bit. Now the difference in the figures will also take into account any additional power draw from the CPU also being under load along with other smaller components like hard drive(s) spinning up and so on.
We do hope to continue improving our testing with better equipment, as our very limited resources will allow.
Thanks for your time. =)
