Will I be bottlenecked?

[Flaco1488]

I have a Sapphire Radeon HD 7770 and upgraded my CPU from an Athlon II X2 255 to a Phenom II X6 1100T because I was mostly CPU bound in games. Should I expect much of an improvement? Or will I still be bottlenecked?

[miyabwah]

There will only be slight improvement. Only 200% performance difference or so. No bottleneck.

Depends what games, in games like ARMA II it will probably be a bottleneck, but in bf4 it will perform admirably. I would recommend overclocking that beast to minimize any bottleneck you might encounter.

You'll be fine, but why a 1100T? Are you getting it off a friend?

I got an 1100T because I started out with a Lenovo H405 pre-built rig, which had an AM3 socket. So I figured the cheapest, most effective upgrade was an 1100T, until I bought it and found out the motherboard wouldn't support a 125w TDP. Then I bought a new mobo, which wouldn't support the custom Lenovo front panel connectors. Then I had to buy a new case, and before you know it I have a custom setup lol. So I have an AM3+ socket now, but I already bought the 1100T, plus I've read that the FX series was kind of a disappointment and in ways inferior to the Phenom II X6 series.

I disagree with this my 1100T OCed couldn't keep up with my GTX 770 Lightning. I ended up getting an 8350 and the difference was 10-15 FPS

The 1100T will do fine.

 

I have 1100T + 3x 7970's in Trifire and I am running 5760x1080 resolution and all I can say is that BF3 Ultra runs smooth. BF4 beta ran fine. And so does many other games.

I am getting 97-99% utilization of GPU cores on all 3 GPU's and they are running at 1095MHz core clock and 1425MHz memory. The 7970's are the reference non GHz variant aka old.

The 1100T is at stock clocks and boosts all 6 cores to 3,7Ghz. I had the CPU OC'ed a couple months ago to 4Ghz accross all cores but to be honest in games I have not noticed a big difference between stock clocks and OC'ed ones.

Pumping up my GPU clocks from 1050MHz to 1100 or 1095 had a greater effect in FPS.

 

GPU bottleneck occurs when your GPU utilization during for example gaming is significantly lower than 85-100% AND your CPU is running close to 100% constantly.

Check out Jayztwocents on youtube for bottleneck testing:

 

That said; I do have an AM3+ mobo and I am going to get an 8350 for it to max out the life span of the mobo. The improvement for 8350 over 1100T in some tests is less than 10% and in terms of games it is less than 10FPS. My 1100T will move to my sisters rig and power two R9 290's.

Talking about the two 290's, they are currently getting 100% GPU utilization in BF3 and Max Payne 3 with Phenom II X4 965 BE (stock clocks) while running 2560x1440 at Ultra settings.

Some games like MMO's (and sometimes RTS games) are CPU bottlenecked. AMD's are straight up horrid in Guild Wars 2. The newer ones aren't horrible in WoW, but still behind I3's.

 

FPS games and most single player games are GPU bound. All depends what games you play. If you could care less about MMO's? AMD's are fantastic. 

 

Look at a AIDA 64 FPU Julia test. That will tell you how you will fair in some of these MMO's, RTS's. Floating point is all that matters, because the optimization is horrid and usually the game only really runs on 3 cores. 

 

My 4770k at 4.5 ghz is like 36,000. A 8350 is like 13,000 something. Your chip is almost as fast as a 8350 in floating point, so unless you gave the 8350 a hefty OC? Performance in a 3 core game wouldn't improve much at all.

True, even an overclocked 1100T to 4.2GHz will still cause bottlenecks of 10-15FPS in CPU demanding games.

 In my experience the 1100T runs games just fine for now at least. Haven't played on Intel platforms so I can't comment on those.

 

I'll have to see how the 8350 changes things once I get it.
