The Skylake Core i3 (51W) CPU Review: i3-6320, i3-6300 and i3-6100 Tested
by Ian Cutress on August 8, 2016 9:00 AM ESTGRID: Autosport
No graphics tests are complete without some input from Codemasters and the EGO engine, which means for this round of testing we point towards GRID: Autosport, the next iteration in the GRID and racing genre. As with our previous racing testing, each update to the engine aims to add in effects, reflections, detail and realism, with Codemasters making ‘authenticity’ a main focal point for this version.
GRID’s benchmark mode is very flexible, and as a result we created a test race using a shortened version of the Red Bull Ring with twelve cars doing two laps. The car is focus starts last and is quite fast, but usually finishes second or third. Both the average and minimum frame rates are recorded.
For this test we used the following settings with our graphics cards:
| GRID: Autosport Settings | |||
| Resolution | Quality | ||
| Low GPU | Integrated Graphics | 1920x1080 | Medium |
| ASUS R7 240 1GB DDR3 | |||
| Medium GPU | MSI GTX 770 Lightning 2GB | 1920x1080 | Maximum |
| MSI R9 285 Gaming 2G | |||
| High GPU | ASUS GTX 980 Strix 4GB | 1920x1080 | Maximum |
| MSI R9 290X Gaming 4G | |||
Integrated Graphics

The difference between the APUs and Intel CPUs again shows up to a 33-50% difference in frame rates, to the point where at 1080p medium the integrated graphics do not break the minimum 30 FPS barrier. The GPU frequency and L3 cache again shows up the i3-6100 compared to the i3-6300.
Discrete Graphics

With the discrete GPUs, there are multiple avenues to take with this analysis.
On the low-end cards, the choice of CPU makes little difference in our tests.
On the mid-range and high-end cards, the power of the CPU makes more of an effect with AMD discrete cards than NVIDIA discrete cards, except with the AMD Athlon X4 845 in play. When using an AMD discrete card with a mid-range GPU, the X4 845 plays well enough with the i3 parts for its price, but falls away a bit more on the high-end AMD discrete GPU. With NVIDIA GPUs, the Athlon X4 845 sits at the bottom and the main challengers are the FX parts.
So for EGO engine rules, it would seem to be:
AMD Carrizo CPU + AMD discrete GPU is OK, the lower powered the GPU the better.
AMD FX CPU + NVIDIA discrete GPU is OK
Intel CPU + any discrete GPU works well.
One could attest the differences between the discrete GPU choices to driver implementation, IPC, or how each GPU company focuses in optimizing for each game at hand (frequency vs threads vs caches).

Looks like even a Skylake i3 may be able to retire the venerable 2400/2500K, higher frame rates and better frame times at that. However a native quad does prevent larger dips.Kevin G - Monday, August 8, 2016 - link
I have a feeling much that is due to the higher base clock on the SkyLake i3 vs. the i5 2500K. Skylake's IPC improvements also help boost performance here too.The real challenge is if the i3 6320 can best the i5 2500k as the same 3.9 Ghz base clock speed. Sandy Bridge was a good overclocker so hitting those figures shouldn't be difficult at all.

That's true, overclocked the difference would diminish. But you also get modernities like high clocked DDR4 in the switchover.At any rate, funny that a dual core i3 can now fluidly run just about everything, it's two cores are probably faster than the 8 in the current consoles.

Benchrmarks don't tell you about the hiccups when playing with a dual core. Specially with things like Crysis 3 or even worse ROt Tomb Raider where you get like half the fps just by using a dual core bs a cheapo Athlon 860K.gamerk2 - Monday, August 8, 2016 - link
That's why Frame Times are also measured, which catches those hitches.Samus - Tuesday, August 9, 2016 - link
I had a lot of issues with my Sandy Bridge i3-2125 in Battlefield 3 circa 2011 with lag and poor minimum frame rates.After long discussions on the forums, it was determined disabling hyper threading actually improved frame rate consistency. So at least in the Sandy Bridge IPC, and probably dating back to Nehalem or even Prescott, Jackson Technology or whatever you want to call it, has a habit of stalling the pipeline if there are too many cache misses to complete the instruction. Obviously more cache resolves this, so the issue isn't as prominent on the i7's, and it would certainly explain why the 4MB i3's are more consistent performers than the 3MB variety.
Of course the only way to prove if hyper threading is causing performance inconsistency is to disable it. It'd be a damn unique investigation for Anandtech to do a IPC improvement impact on it's affect on hyper-threading performance over the years, perhaps even dating back to the P4.

HOW ON EARTH DID I MISS THIS?!?!Thank you for introducing me to Intel's tech known as "Jackson!" This is now *SO* on my "To Buy" list!
Thank you Samus! :-D

Neah, I went i5-2500k -> i5-6600k and there's no noticeable difference. The best part of the upgrade was those new I/O ports on the new motherboard, but it's a sad day when you upgrade after 4 years and the most you have to show is you new M2 or USB 3.1 ports (and USB 3.1 is only added through a 3rd party chip).Sure, if I bench it, the new i5 is faster, but since the old i5 wasn't exactly slow, I can't say that I see a significant improvement.
Now, if you mean that instead of getting an i5-2500k one can now look at a Skylake i3, I'm not going to argue with you there. Though (money permitting) the boost speed might be nice to have anyway.

This is a poorly educated comment:a) Your perceived speed might be limited by your storage
b) You don't utilize your cpu's multitasking abilities fully(all cores)

Why did you continue to post your comment if you believed you were making poorly educated points?
