Bulldozer Trades Blows WIth Sandy Bridge?

post #1 of 19
Thread Starter 
Hey, just unsure if i should go bd or sb

Im wanting to run it with 2 480s, will it be bottlenecked?

The $170 amazon 8150 deal seems really good, and i have heard alot of people saying it trades blows with sandy

I browsed the bulldozer club and they say the same, just want confirmation so i dont waste my money


Cheers
:P

Bulldozer trades blows with sandy when looking at threaded workloads.
For gaming, the 2500k absolutely crushes the 8150, particularly in SLI/CFX-scenarios

Easy, unbiased answer. Find yourself the two best 3dmark11 runs using 480 sli on conventional cooling. (If gaming performance is what you're after) Compare for yourself.

Unfortunately, yes. An i3-2100 may beat the FX8150; an i3-2100 beats the 4100, with the difference becoming more obvious with better graphics cards (and they just went up to a 6950).

http://www.tomshardware.com/reviews/fx-4100-core-i3-2100-gaming-benchmark,3136-9.html

With a nicer card, even the dual-core Sandy Bridge cards will beat an FX 8120. An i5-2400 will beat an OCed FX 8120 easily.

http://www.tomshardware.com/reviews/gaming-fx-pentium-apu-benchmark,3120.html

And your setup is stronger than a 7970. According to TH, you notice a difference if components are 3 tiers or more apart on their hierarchy, and the FX 8150 is 3 tiers below the Sandy Bridge quad-cores.

So if gaming is your purpose, then the Sandy Bridge offerings are noticeably better. And I like AMD...

I'd personally go with Sandy Bridge a 2500k or a 2600k, Games only use up to 4 cores if that theres no point in buying an 8 core cpu when games dont yet use 8 cores. I moved from 1100T to a 2600k and notice a huge difference. In answer to the bottleneck thing I run 2 GTX 580's with a 2600k
and have had no bottleneck with my setup whatsoever.

Not entirely true on the SLi/CF. Yes, the CPU is weaker by a bit, however, the chipset makes up some of that difference. The Intel P67/z68/z77chipset only provides 16 lanes to a GPU setup, mine are running in x8/x8 right now on my 2600k. On a Bulldozer rig, they'd be in x16/16, while that's only really a 2-4% difference on each card in terms of output, it'll make up a significant part of the speed difference between the chips.

It depends on the game, really. Many GPU limited games will be just as fast on AMD, but if it's really CPU heavy, like Starcraft2 for example, expect the Intel chip to be ahead.

3DMark11 isn't nearly as CPU-hungry as Battlefield 3 or The Witcher 2, might as well get your money's worth with a 2500k.

For gaming, a lot of people were dead wrong. Sandy Bridge >>>>>> Bulldozer.
Also, the 'cheaper' CPU prices are somewhat offset by motherboard costs. A good overclocking motherboard for Intel can be $30-$40 cheaper than a good overclocking motherboard for Bulldozer. Then there's the much lower power draw too...

your 480's wont be bottlenecked with a healthy OC, but no doubt a 2500k would be better!
