i5-2500K to i7-770T, will I see it slower?

[chrislip]

I am looking to finally upgrade my 2500k and am a bit more energy conscious so have been looking into the T model CPUs (35W TDP). I have one of these in my home lab and am happy with it, however I use my main PC for gaming and it is a more day to day PC so I don't want to notice a slowdown from my 2500K. At the moment my 2500 is running at 4.4Ghz fine, and I know by getting the T I will be losing the overclocking potential. On the other side of the coin is that the i7 has more cores and is a newer model so will this be enough to make up for the shortfall on clock speed? I'm not a hardcore gamer, just play the likes of Diablo 3, Skyrim and other RPGs.

Thanks Guys!

Don't get hung up on power consumption as you are only talking about pennies. My entire pc at idle only draws 72w at the wall and anything between 122w and 254w at the wall while gaming (depending on the game). Even with the gpu heavily overclocked I haven't even hit 300w at the wall while benching. I reckon your 2500k at 4.5Ghz has more grunt than a T version of a i7 and wouldn't even consider one for a gaming pc. Don't forget the the turbo clock of the i7 7700T is just a single core at 3.8Ghz. It's probably 3.6Ghz for all cores.

The Ryzen APU's are out soon.

I'm running an i7 3770 in my under the tv gaming / htpc computer.

- I can overclock the all core boost to 4.1 with a z77 board and run 2400 ram.
- you can run nvme drives with an adapter and a bios mod. I'm running a pm961 128gb as a boot drive.

I'd recommend the same in your position.

What are you using to measure power draw?

 

[pastymuncher]

I have a Zalman ZM-MFC2 fan controller which displays live power draw readings. It matches the readings on my plug in power monitor so is pretty accurate.

The T version is fantastic for low power builds. I have tested the 7700T against the 7700K - it achieves 75% of the performance with 33% of the power consumption. More importantly, no matter how the K undervolts, it just doesn't beat the T in terms of frequency for the same low voltage.

stock i7-3770t id says would be slower than what you have... it will take years to save the cost of the CPU in electricity so unless you need low power for some reason there is no point..

I recon 2500 to i7-3770 you gain ~30% if the clock speeds are the same

The T series is not for electricity bills - instead, it's for better cooling in smaller machines. Cases like Louqe, Dan Cases SFX-A4 etc cannot be compatible with larger CPU coolers. A 7700T fits well with a Noctua L9i. Given that nowadays CPU isn't that important for gaming performance, such smaller cases serve very well for gaming purposes when coupled with a graphics card like the GTX 1080 Ti.
