Ivy Bridge 3770K Gaming results vs Core i7-920 at 4.2GHz
3DMark 11 and Vantage are useful tests to track changes within the same system and they are often used to give a rough comparison between platforms.
First up we look at Vantage and HD 4000 Graphics.
It isn’t terribly impresive especially compared to a GTX 680; here are the results with the CPU and GPU both at stock settings:
Now we overclock our Core i7-3770K to 4.2GHz and our GTX 680 speeds are increased to their maximum without added voltage by +150MHz on the core and +575MHz on the memory clocks::
Now let’s look at 3D Mark 11. First up, HD 4000 CPU graphics:
Now lets check out the score with an overclocked GTX 680 and with our Core i7-3770K:
Let’s look at Intel HD graphics performance:
HD 3000 versus HD 4000 CPU graphics
The improvement over HD 3000 Graphics is significant. Finally, DX9 and DX10 games can play relatively smoothly at 720P and DX11 is a possiblity using HD 4000 graphics. Shogun II had issues since the recent 5GB patch and we could not run it at all with our GTX 680 as its hardware was being misidentified in the game.
Now let’s compare our overclocked Core i7-920 versus our Ivy Bridge i7-3770K using a GTX 680 at both stock and also overclocked speeds.
The Game Benchmarks with the GTX 680
Here are the benches for the Core i7-920 at 4.2GHz versus Core i7-3770 at stock 3.5GHz and at 4.2GHz; the stock speed turbos to 3.9GHz so our overclock to 4.2GHz is mild. All games have their setting completely maxed out and levels of AA are identified on the chart.
The first results colums is the Ivy Bridge i7-3700K at stock paired with a stock GTX 680 versus the Core i7-920 at 4.2GHz with the same stock GTX 680. The third column is the Core i7-3700K with an overclocked GTX 680 versus the Core i7-920/overclocked GTX 680 in the 4th column. Finally, the last column is the Core i7-3770K overclocked to 4.2GHz paired with the overclocked GTX 680.
As you can see, the stock Ivy Bridge Core i7-3770K trades blows with the highly overclocked Core i7-920, and when Ivy Bridge is overclocked to 4.2GHz – only +300MHz above the Turbo boost speed of 3.9GHz - it pulls away from the older CPU in games that are not GPU-limited. There are some oddities that we experienced with drivers and games besides with Shogun II. F1 2010 had artifacting and a couple of other games rather strangely favor the older platform. We will continue to track this as our evaluation continues this week.
We can’t wait to find the maximum overclock of our Core i7-3770K using our new Noctua flagship CPU Cooler, the NH-DH14. We expect that except for GPU-limited games, we will leave our old platform in the dust!
Let’s head for our conclusion.
