2x A10 chips and Phenom besting an i7 920 with its HT and triple channel ram?
The A10 I have in my HTPC while fine for general stuff is certainly no workhorse and I wouldn't want to do loads of intensive stuff on it.

Maybe because AMD has been working more closely with Adobe now. You do realise that CS has added OpenCL acceleration due to AMD and Apple,so it does make sense that at the same time they have been doing optimisations for their CPUs too. Remember this is also for only one of the current Adobe products too,so there is probably different relative positions with other software they make like say Premiere Pro,so balance to the force might be restored!! :p

However,Lightroom benchmarks are thin on the ground,so this is why I posted it - plenty of sites test Adobe PS and PP.

Edit!!

Remember that the Core i7 920 has quite a low base clockspeed and low Turbo,so is beaten in many applications now by newer CPUs from both AMD and Intel.

Overclock it though,and it shows a greater percentage increase in performance due to the low Turbo,and it is why the Core i7 920 overclocked still holds up very well.

Have an i7-2600K myself but clocked at 4Ghz and have no performance complaints really.

Frankly the test is rather rubbish. There's no detail on exactly what they did, all it says is "converted from RAW". What does that mean? Processing the RAW and generating a preview? What size preview?

Overall, we have converted 30 raw image files from a Nikon D800 with a total size of 1.23 GiByte.

Plus the video also shows exactly what they did,which is better than most sites bother to do TBH!

Its in German but indicates they generated 30 jpegs at the same resolution as the RAW files. They used sRGB and 87% quality for the jpegs.

Only 4GB Ram used

Probably a typo,since here is an earlier review of the Xeon E3 1230 V3 the previous month:

http://www.pcgameshardware.de/CPU-Hardware-154106/Tests/Xeon-E3-1230-v3-Test-1099616/


Lightroom 5.3 (sec)
Core i7-4770K 174
Xeon E3-1240 v3 176
Xeon E3-1230 v3 182
AMD FX-9370 172
Core i5-4670K OC 4,3GHz 161
Core i5-4670K 181
AMD FX-8350 181

8GB of RAM used in dual channel for that test for at least the socket 1150 and AM3+ chips,and the scores are exactly the same. They missed out the "2X" part in the chart.

Maybe if someone knows German,perhaps ask in the review thread??

It also means the DC chips,especially the Core i7 4790K running at 4GHZ to 4.4GHZ will be great for LR 5.3 too if you are not overclocking.

A Haswell Core i5 at 4.5GHZ is probably going to get quite close to a Core i7 3960X.

Edit!!

It seems HT does not make a massive difference,and there is not massive core scaling above 4 cores either.

So a Core i5 4670K,fast drives and a decent amount of RAM seem to be the best compromise for LR ATM.

Right,I translated what is said in the chart.

It says:

"4GiB DDR3 RAM pro speicherkanal"

Google translate says:

"4GiB DDR3 RAM memory per channel"

So that is 8GB for the socket 1155,socket 1150 and AM3+ platforms,12GB for the socket 1366 platform and 16GB for the socket 2011 platform.

I didn't notice that, but I still stand by my original point. They don't seem to have any (Decent) low powered chips on that list.:p

The 4570T is about the slowest low power processor Intel do, it's about half the speed of the ones I mentioned according to http://www.cpubenchmark.net/

Looking at the clockspeeds,I would say the Core i5 4690S should be within 10% of a Core i5 4670K:
