PENTIUM G620

does anyone have any experience with these? do they OC at all, are they pretty good @ stock?
unable to find any real benchmarks or info on this chip.

Looking at the Intel spec finder on the Intel website it looks to be a cut down i3 with no Hyperthreading and a previous generation GPU?

I'd imagine they overclock quite well providing they are not multiplier locked (which is likely to be the case).

paradisiac · 17 Jun 2011 at 15:25

so not ideal for gaming?

olivier renault · 17 Jun 2011 at 17:13

no, pretty crap. I would rather have a i3-2100 or some such. No overclocking but at least you can resell pretty easy. ... if you are still thinking of getting that temporary CPU

In fact it might be worth checking out the member market and second hand for one.

its nearly double the price though.
any idea what the difference is between the G620 and G620T are as the G620T is 400mhz slower but more expensive.

Max tdp on the T is 35w instead of 65w so slightly lower temps and reduced power consumption I would imagine.

ok thats kool. how would it compare to my Athlon X2 555 BE does anyone know, or are these chips that poor no one really has them?

DragonQ · 17 Jun 2011 at 17:34

I wouldn't think it's much of an upgrade over an Athlon X2, especially as you have a Black Edition.

i just want something to tide me over until i sell my current mobo/cpu. but i dont want to do something which will end up slowing the pc down, incase i dont sell the mobo/cpu quickly or for as much as i need. if its a sidestep rather than an up/downgrade then that will be fine as i would have the motherboard i wanted and a working pc until i sold my current bits.

Are you selling the computer in you sig for a G620? Because the tri-core will easily beat that.

i am thinking of selling the 890FX and X2 555BE in a cheap case, 2GB ram, cheap gfx, a smallish hdd, dvd drive and either win7 or vista to fund a 2500k or 2600k depending on how much it sold for. so whilst im waiting for that to sell i want to get the ASRock Z68-Extreme4 mobo and a cheap cpu.

I don't see any cheap 1155 Intel CPU that you can buy which will match a triple 3.8ghz AMD so you're going to have to put up with some kind of performance drop in the mean time, if I were you I'd try to sell first and just go a few days without a PC while you order the new stuff (if you can cope!

).

the thing is, to sell it would be stripping it all and moving to a different case. which would mean no HD6850 setup so that would be more of a hit than dropping the cpu, i think :confused:

what sort of hit would i take dropping to a 2.6GHz DC? would it just be a case of dropping from high to medium, or going right down to low? or would dropping res from 1920x1080 do the trick. if its going to be a few fps here and there (i have to have vsync on anyways else i get screen tearing on most games) then i probably wouldnt notice the hit for a short term with what i currently play.
because my pc has been awkward to use up until last week i havent really had a chance to game. now it has its own desk and all, i will want to use it more, hence the itch to get things going with an upgrade.

It's not really to bad a chip, in real performance terms it's little over half the raw power of an i5 750. More info on the following links.

thanks for that. now have the money so will hopfully order mon/tues and will do some bench test to compare it to my 555 stock and unlocked/overclocked and see. i cant really see it will be too much of a hit as you say, the chips seem to fair pretty well, and with the tests here it seems to fair pretty well in games. i guess losing a core is the biggest thing, but as mine isnt supposed to have the extra core anyway, then be intresting to see how it rates compared to it.

You cannot overclock any of the current socket 1155 Pentium and Core i3 processors. Also,your overclocked and unlocked Phenom II X2 is going to be much faster than any of the current Pentum processors in most games:

http://en.inpai.com.cn/doc/enshowcont.asp?id=7970&pageid=7921

The Athlon II X3 lacks L3 cache and your unlocked Phenom II X4 is running 700MHZ higher too. The Pentium G840 is the same price as the Athlon II X3 455 which is clocked 6.5% higher than Athlon II tested.

TBH,I would stick with what you have until Bulldozer is released. On top of this prices will probably improve on the Intel processors too. Buying stop gap processors is not really cost effective and you might as well save up another £100 for a Core i5 2500K if you intend to move over to a socket 1155 based setup.

just going on the cinebench results for the G620 then it falls between mine at stock and mine unlocked and overclocked :
X2 555 Stock

X3 B55 @ 3.7GHz

G620 (from here)

555 - 1.89pts
B55 - 3.21pts
G620 - 2.03pts

im not sure how much cinebench is affected by my 2 HD6850s though, because they wouldnt of been used for the G620 test.

A £130 to £140 3.2GHZ Phenom II X6 1090T scores 5.73 in CineBench 11.5 and around 7.26 when overclocked to 4.1GHZ:

http://www.guru3d.com/article/phenom-ii-x6-1055t-1090t-review/12

However, CineBench 11.5 performance is not a good indication of gaming performance AFAIK.

Edit!!

If you are doing a lot of rendering though I suspect an 8 core Bulldozer CPU is going to be quite powerful.

it was the only like for like benchmark i had

i agree that the 1055 or 1090 would be better value, but i will then be left with a 555 that i dont need and will have no real resale value (i have an X2 250 for testing at the moment). with the G620 though, i can sell my stuff as a usable system and then upgrade the cpu, keeping the G620 as a spare 'test' cpu.
i kind of had my heart set on a BD build, but with all the delays and my inability to save, i think a SB build will be best and then a Llano build as a media pc nearer xmas.

An X2 555BE sells for between £45 to £55 on the famous auction website.

I would also open a separate savings account and put the money for your upgrades into this. Don't touch it until you are ready to upgrade.

HardOCP said that they would be having a special AMD event in July:
