Analysis of Kaveri's Downclocking CPU to 3.0GHz when iGPU is under full load - Page 4

If you are looking for a UE3 game to test Bioshock Infinite is UE3 and has its own bench utility. It only shows fps tho.

Just curious, what kind of speeds does your drop to? Unfortunately i'm stuck with just the igpu and the cpu dropping is a real struggle for even this thing. The funny thing is, with the graphics on low and a low enough resolution I can game fine otherwise even on many modern titles. Tomb Raider is actually fairly easy to run considering it seems to not care what cpu is running. I was looking to maybe replace this laptop down the line with one that had the discrete gpu. I don't game a crazy amount on the laptop but it drives me nuts when the cpu downclocks and the performance tanks so I was assuming the discrete gpu caused it not to drop.

Ooops. The whole point of testing in this thread is to show that GeAPM throttling causes all gaming performance to drop to the same level as if you booted with the throttled clockspeed by default.

So I guess we can assume that your results showed GPU limitation.

I don't game a crazy amount on the laptop but it drives me nuts when the cpu downclocks and the performance tanks so I was assuming the discrete gpu caused it not to drop.

When all four cores are loaded (iGPU idle) it drops to 2GHz. When the CPU + iGPU are loaded it drops to 1.8GHz, which is A6-6310 speed. AMD falsely advertise these chips as clocking from 2-2.4GHz, as they clock from 1.8-2.4GHz. I had my suspicions when I bought this laptop so I wasn't surprised when it clocked down to 1.8.

 

What is interesting at Beema is that when the dGPU and CPU cores are loaded drivers offload certain tasks to the iGPU. This is meant to boost performance but while it may help the weak dGPU it forced the CPU to run even slower.

 

But even if the CPU stayed at 2GHz it would still be too slow for modern games. There is no way I can play games made in the past few years on it. The most demanding game I can play is CIV V (love the game) but it's a small map with only a few CiV's and city states. There is no way I would play a large map with a lot of CIV's and city states, end game turns would take forever. League of Legends runs perfectly on the iGPU with settings at low at 1366x768. Usually I use the laptop to watch films while I play games or do other things on my PC so it serves its purpose very well and I won't replace it for another few years at least.

 

Older games such as Homeworld run perfectly but the second one is over a decade old so it's no surprise it runs well (first one was released in 1999, second one in 2003 and they are still the best fully 3D RTS games.

Thanks, good to know. I was dissapointed seeing it drop down so much but it's the nature of a 15w tdp I guess. I threw in 8gb of ddr3 1866 and a 250gb crucial bx100 to at least speed up daily use on the go and the bx100 is very efficient for even a SSD so battery life improved as well. I paid a good deal less than $300 for this thing and it came w/ 6gb DDR3 1600 and the standard 500gb WD Blue drive which I now use as an external usb drive. Anyways, it's a good laptop and I honestly use it mostly for Counter Strike, Counter Strike:Source, Team Fortress, Quake Live, UT99, Sim City, and of course it's my go to nes/snes/n64/ds emulation machine.

Notebooks/Netbooks/Ultrabooks/Sleekbooks should come with ssds by default. I had a netbook with a 62wh battery that came out at 11hrs practical daily use between charges that got replaced with a 6-cell 48 wh 9-hr effective battery. The moment I switched the hdd to an ssd I gained one and a half hour longer stretches out of it and its controller wasn't even an efficiency oriented one.

yes, it's sad in mid 2016 this still isn't a reality. Less weight, less heat (not important in laptops right?) more battery life, much better performance. Not that much more expensive.
I would have payed double the worth of my laptop's SSD for it to have come with the machine instead of having to literally pull the thing apart(thanks ASUS) just to install it.

AMD never claimed it was a gaming chip, they advertised it as a ULV chip and I knew I wasn't getting the best and didn't care. I have this 4.5GHz 8 core beast so I don't need a powerful laptop.

I bought mine two years ago and SSD's weren't as cheap then as they are now so in a budget oriented laptop it doesn't really matter whether they put an SSD or not. In this category users want the cheapest thing possible and SSD will just add to the price.
