8120 and 8150 same cpu, truth or rumor?

Found a few posts out there suggesting that the 8120 and 8150 are identical (with a little tweaking) and there was no reason to purchase the more expensive model. Is this true?

99% true, 8120 and 8150 are the same chip(same module count, same L2, L3 etc) except the higher operating frequency the 8150 has. IPC and performance Clock per Clock are the same.

Only difference i know is with Xtreme OC (LN2 etc), 8150 OC higher. No difference in Air/Water cooling as far as i know.

First Greek OCer at 8GHz (Nickname : AMDnord).

They are the same. Different clock speed is all.

Correct me if I'm wrong

You're wrong :D well, not really...

The 8150 is higher binned under the same TDP. They could essentially be the same CPU still (that depends on yields, though), but you'd have a better chance of having a 95W 8120 the "same" as a 125W 8150. I guess how close they are would depend on the version of the chip.

I've yet to see a 95W 8120, but they are out there.

8150 is a better binned chip. It *should* require less volts to hit the same clock. However, it should not much matter unless, you are a hard-core overclocker.

The FX-8150 and FX-4100 are the same CPU also. Except the 4100 has 2 modules disabled, and different clocks.

I think by the "same" people mean they're the same bin quality, but just rigged to be different clockspeeds.

Same pile of cheese, different cuts to please.

Check this.

Doesn't it suck that you can't do the Unlock magic?



EDIT: Overclocking-wise, 8120 seems to be just as good.

All the answers and no explanation.

In semiconductor manufacturing, a huge chunk of the cost of making processors is designing and making the mask, which only needs to be made once. This means that there typically are very few different chip models being manufactured at once. For example, on Intel side the cpu models i5-{2300, 2310, 2320, 2400S, 2405S, 2400, 2500T, 2500S, 2500, 2500K} and i7-{2600S, 2600, 2600K, 2700K} are all the exact same chip. At present, actually every single FX cpu is the same chip.

However, not every cpu made of the same mold is identical -- some run at higher frequencies, some can function at very low power, some leak more (so they run hotter), and some have manufacturing errors. This means that after being produced, chips are binned -- that is, they are tested and sorted for different products. At this point their clock speed is set to something, and if they have faulty cores, they are turned off. So, purchasing the higher model number would presumably get you a chip that's from a bit better bin. Realistically, given how little difference there is in the stated cpu speed of the chips, this probably doesn't matter.

I'm glad you guys liked it.

I told you this thread would not be locked, btw. They can't. It is metaphysical.

It's inevitable :D
AMD flagship FX 8350, the one that will replace the current flagship in the AMD world known as FX 8150, will enter in production in Q3 2012. We don’t know if it can make it for a launch in the same quarter, but it looks like that is the plan.

AMD FX 8350 is based on eight Vishera 32nm cores that will support Enhanced AMD turbo core technology, DDR3 1866 and fit the same AM3+ socket. At this time AMD doesn’t mention any clocks.

The FX8150 runs at a guaranteed 3.6 GHz and the FX8120 runs at a guaranteed 3.1 GHz.
