Core M-5Y71 or i5-4300Y for best game performance?

Looking at the Dell Venue Pro 11 there's two models:

7130 -- i5-4300Y CPU (HD 4200 GPU)

7140 -- Core M-5Y71 (HD 5300 GPU)

The 7130 has a lot of information on this forum about the results of using Throttlestop to increase performance markedly.

If a 7130 has thermal throttling "disabled", what are people opinions on which would be faster for 3D Windows games? On paper the Core M appears faster but it appears that under sustained loads it's throttled which would make it a slower option compared to i5-4300Y with throttling removed.

 

Why even bother gaming on a venue pro ?

 

Because he wants too.
I play on my T100 as well from time to time.

 

overheating will probably kill the BGA and we will laugh then It's not designed for that use..

 

I'm guessing OP won't be trying Cruisis 3, so not sure why you straight away presume it will overheat and die.
I've played a number of games on my T100 (HL2, CiV, South Park, etc.) and it hasn't died yet.

 

Ahah, still, my experience with a lot of friends laptop that are pushed to the limits when gaming and had BGA reballing problem says that it's dangerous, may be now with TDP strict limitations machines may resist better

 

The HD 5300 is much faster than the HD 4200.

Intel's onboard graphics are much better than they used to be. Heck my HD 3000 on my old dual core Ivy Bridge could do things I didn't think it would be able to. No AAA titles at high settings but I was even able to run PS2 emulators at 1600x900 with no slowdown even with the internal resolution tripled or quadrupled. The HD 4000 was a huge leap over that, then the 4600 but the 5300 beats them all rather handily.

 

Why bother answering?

All CPUs have thermal shutdown now ie. if they overheat they throttle.

Yeah on paper it is however with these CPUs they control their speeds according to various parameters including temprature (eg. chassis temp) and power draw (in order to save battery). Unfortunately this can lead to the situation of the CPU and/or GPU being throttled and that extra performance goes down the drain if you run them in a sustained way such as games.

Doing more research it seems like the Core M chips are just too constrained for games and I'd be better off getting a device with a i5/i7 that is able to be "unlocked" using software or laptop cooler such as Surface 3/4 (higher performance at the cost of battery and more heat). Whilst the Core M (HD 5300 iGPU) devices will *start* off with better performance after a few minutes they are throttled and the performance drops to a crawl compared to "unlocked" i5/i7 iGPU

 

To mention the bga problem and the limited performance..

Depends on the bios, e.g., Dell Insprion N5110 overheat (even if it's not bga, still unable to properly dissipate heat, so people who uses them to game kill their laptop within monthes/ 1 year max) and other BGA problems..

 

You're going to have issues with throttling with either option. These aren't meant for anything other than burst performance. If gaming is important to you I'd seriously recommend getting something with a real CPU.

They're both locked TDP chips and Haswell uses more power than Broadwell does. Once you hit that TDP you're going to throttle, end of story. Using ThrottleStop is your choice but I'd recommend against it in such a device. The throttle isn't just there to protect the CPU but the other components in the system as well.

 

i actually have to say i owned a M core laptop a samsung ultra book with the 510 which beats all of the above...when gaming it had extremely poor performance compared to a i3 i5 i7 igpu. this unfortunatly is one of those cases where you have to try it out and see for yourself...and i dont think it was throttling. that should not be an issue on a tablet hybrid. get the i3 or i5 if your after gaming on the go...

 

That isn't what users are reporting on this forum with Venue Pro 11 (i5-4300Y) or Surface Pro 3 (i5-4200U) devices after using Throttlestop and/or mitigating other throttling measures such as cooling the chassis. They are reporting that the devices run unthrottled for over an hour of sustained 3D gaming or stress testing. I think Haswell is much more suitable for this task than Core M because it has higher TDP.

There isn't "a throttle", there are many ways throttling can be applied depending on how the manufacturer wants to implement it. This is why Surface Pro 3 throttling can be mitigated by cooling the chassis because MS decided to throttle so the chassis doesn't warm up. Just because it is like this does not mean throttling won't begin if CPU temps gets >95C (or whatever it is). Another major throttling reason is battery life etc.

I hear what your saying regarding performance but it's for a particular situation and I don't want to fork out a lot for discrete graphics.

I'd rather go on other people experiences rather than trying it out on my own But I agree it seems like Core M really is a crap shoot ATM.

What makes you think the performance issue isn't throttling?

 

i was monitoring the temps they never went above 63c

 

Temperature isn't the only thing that causes throttling. The chips are locked to a TDP of 4.5W - once it hits that, the chip throttles regardless of the temperature.

 

Well it wasnt throttling. Performance was poor from start to finish i returned the laptop. And i actually didnt know throttling could happen due to tdp thanks..
