It'll mostly be for work purposes, and I'll most likely just play SC2 and some older games like oblivion occasionally on it. All other specs should be similar, both being Thinkpads. Which one would be faster and by how much for gaming? Thanks! edit: both have integrated intel HD graphics, the i5 being sandy bridge HD 3000 and the ivy bridge i3 with HD 4000. | ||

At the beginning of games everything is >100 FPS, but later on nothing is consistent. Could you transfer saves? O_O | ||

Oblivion savegame playthrough - Outdoors, forest - 1366 x 768, medium settings: i3: Min. 19, Max. 43, Avg. 35.449. i5: Min. 24, Max. 60, Avg. 42.272. SC2 replay - 150/200 battle 1v1 - 1366 x 768, lowest settings: i3: Min. 14, Max. 62, Avg. 39.731. i5: Min. 38, Max. 85, Avg. 56.911. Really surprising results TBH, I guess the i3 really is a low-end part. I was completely ready to believe you guys too thinking HD 4000 must > HD 3000, even though it's an i3 vs. an i5. So yah, Sandy Bridge i5 HD3000 > Ivy Bridge i3 HD4000, apparently. | ||

So yah, Sandy Bridge i5 HD3000 > Ivy Bridge i3 HD4000, apparently. Pretty sure that's not true (i got food so cant google stuff atm) but AFAIK there's not multiple igpu's with the same name, hd3k is hd3k and hd4k is hd4k and also, that's a massive performance difference in sc2. 42% higher average? The i5 is on worse architecture clocked only a little bit higher | ||

i3-3310M - 2C/4T, 2.4 GHz, Ivy Bridge, standard 35W TDP HD 3000 - 12 EU, clock speed depends on processor (1200 MHz max on i5-2410M) HD 4000 - 16 EU, clock speed depends on processor (1000 MHz max on i3-3310M) Recheck clock speeds for CPU and GPU (check power profiles too) on a separate monitor while benches are running. It should be closer than that. | ||

Then we have 2.9GHz vs 2.4GHz, which is a lot higher, especially on sc2 where higher clock = higher fps. The results are making sense imo (except too much difference in sc2 but not "that" much compared to the clock speed difference) | ||

The i5 is on worse architecture clocked only a little bit higher Turbo and base graphics speeds vary between different models. All full voltage parts have the same number of EUs though. | ||

And it was on desktop architectures. Then we have 2.9GHz vs 2.4GHz, which is a lot higher, especially on sc2 where higher clock = higher fps. The results are making sense imo (except too much difference in sc2 but not "that" much compared to the clock speed difference) It shouldn't be hitting the 1-core-active-only 2.9 GHz Turbo Boost bin when running games usually, only the 2.6 GHz one and possibly not even that 100% of the time depending on how it's configured and the cooling and GPU load. So 2.4 GHz Ivy to 2.6 GHz (sometimes 2.3 GHz? possibly sometimes 2.9 GHz?) Sandy should be close, mostly a wash. | ||

It should be closer than that. I have done some tests before. If you want to run at max GPU speed, you can't be in a turbo clock with the CPU. I'm really surprised at the results too. I guess CPU speed is all that matters in SC2. Less EUs using less of the TDP share might help. | ||

Some interesting notes: - Overall, the ivy bridge ran a LOT cooler - didn't bother looking at the CPU temps, but the GPU temps for the i3 were averaging 63C and never went above 65C even under 100% load, while the i5 managed to hit 94C! max and averaged above 80C in SC2. Not sure how much of this is due to architecture and how much to the clean fans on the brand new i3. - The Ivy Bridge also consistently used a lot less power - on average, the i3 GPU power consumption hovered around 5-8W, while the i5 were hitting 15W and averaging 12-14W. - Both the i3 and i5 didn't max out on the dynamic GPU core clock in sc2 but did so in Oblivion, they were running at 600-800mhz in SC2 while pretty much hit their respective max. core clocks in Oblivion (950mhz and 1150mhz for the i3 and i5, respectively). Also, the GPUs were rarely under 100% load in SC2, both were hovering around a 40-80% load most of the time. - The i5, with turbo boost, was flashing between 2.9ghz and 2.7ghz in SC2, so I guess that's the CPU pushed to the limit and adjusting between high demand single-threaded calculations and multi-threaded tasks while the i3 sat at a constant 2396mhz. Meh, I gotta say I'm pretty disappointed, was hoping for a slight framerate boost in games with the x230i. Thanks for all the help. | ||
