Lynnfield vs Haswell in Cinebench R15

[Mew]

Since I was bored, I decided to do some calculations to see how much faster Haswell is over Lynnfield. At the same clock speeds, Haswell is 35% faster than lynnfield (35% higher IPC). Haswell achieved 139 in the single threaded test in Cinebench, while Lynnfield achieved 117 at 4.008ghz. Since I don't have the lynnfield system running anymore, I calculated at what frequency my 4690k had to run to get the same score as the lynnfield at 4ghz 1 core turbo. It turns out, Haswell at 3ghz will be as fast as Lynnfield at 4ghz. It seems that Cinebench's scores scale linearly with clock speed. Because of that, I calculated what Lynnfield would achieve at 3.5ghz- the result is 102.375. Because of this, Haswell is 35% faster than Lynnfield at the same clocks.

I did some further calculations. At the stock i5 750 turbos, the 1 core 3.2 (3192mhz) should achieve 93.1796, and the 4 core turbo 2.8 (2793mhz) is 81.53. Overall, Haswell at a fixed 3.5ghz is 70% faster than a stock i5 750 at the regular 4 core turbo of 2.8ghz.

 

Here are my results with more clarity:

Haswell:

3.5ghz 1 core- 139

3ghz 1 core- 119

Lynnfield:

4ghz 1 core-117

3.5ghz 1 core-102.375, so about 102

3.2ghz 1 core-93.1796, about 93

2.8ghz 1 core-81.53, about 82

 

Clock for clock (at same clock speeds):

Haswell is 35% faster

 

For same performance:

Haswell at 3ghz is just as fast as lynnfield at 4ghz.

You should do a gaming benchmark.

I would have, but my i5 750 and p55 board are packed away in storage right now since I upgraded a couple weeks ago. I just wanted to make this post as a psa for those that are thinking of upgrading from lynnfield, particularly the i5 750 to Haswell, the 4670k or 4690k.

Good test report it will help for  lynnfield upgraders.

That seems about right.

On my old 860 I got 129/661 at 4.2ghz.

Another way to put it is Lynnfield is 25% slower than Haswell.
