I know right, they plan on doing the same with GPUs. Capped at 200W if I'm not mistaking.

They did the same thing to microwaves, electric heating and vacuum cleaners. I get their incentive but really my dear computer :/

Such a line of thought reminds me of the Netburst era, when Intel propaganda would use that exact illogical reasoning to defend itself against Athlon. You can't get around IPC, IPC, IPC. As such, Vishera 6300 clocking higher is generally irrelevant. You'd have to find an exceptionally well binned 6300, and get it stable at 5 GHz, in order to beat a decent clocking Thuban at 4.1 GHz. Even if this is accomplished, the 6300 would be set at a much higher vcore, and would be devouring much more electricity than the Thuban. This is why 1100T performance was included in most 8150/8350 benchmark comparos, because an X6 was more comparable in IPC to an octocore BD/PD.

All these pro-Thuban comments are making me want to keep my 1055T @ 3.8GHz. I've got a 8320 coming from another OCner in ~4 weeks, I guess I'll have to see how it performs.

This is utter nonsense. It's not irrelevant at all, especially when Phenom II and Vishera generally having the same per-core performance. The 6300 can not only clock higher, but can do it with ease. It's a no-brainer that the 6300 is the better buy, at least for me. I don't know where people come up with this "6300 must be clocked at 5000 Thz to match Thuban" nonsense comes from. The most CPU-intensive thing I do is PCSX2 emulation (aside from video rendering).

http://forums.pcsx2.net/Thread-CPU-Benchmark-designed-for-PCSX2-based-on-FFX-2

You can clearly see how the Vishera's leave Phenom II behind here. It's because PCSX2 mainly runs on two threads. I know that in multi-threaded scenarios, the shared decoder in the Bulldozer uarch can hurt multi-threaded performance, but you can clock that Thuban at 4.1 or 4.2 where it tops out at all you want, it won't beat a 6300 at 4.8 ghz or anything. For me, the 6300 would be the better buy because as long as I had decent aftermarket cooling and a good board, I'd have no problems keeping a stable high OC with all 3 modules and 6 cores enabled.

You can also click the CPU-Z validations for the Vishera's and see that they mostly have reasonable vcore's as well.

Phenom II and Thuban were good chips, but all this worship needs to come to an end.

Was going to get a 8350 for christmas, think I'll wait.

How is it utter nonsense? Those bench results state exactly what I said; look at the speeds of the BD/PD chips, then look at the speeds of the Thuban/Deneb chips. When a BD/PD beats a Thuban/Deneb, it's clocked in the neighborhood of 5 GHz, and the top scoring Thubans/Denebs are in 4.2 GHz territory. The point is that Vishera doesn't leave Thuban in the dust; it meanders in the same neighborhood, albeit a couple of blocks down the street. Both uarchs are good, but Vishera is absolutely not conclusively better.

Let's not start this again, seriously. When it comes to 95% of tasks and especially gaming, PD mops the floor with Phenom II. Stars was very good, I have an Athlon II X4 640 right here (will drop in an FX octocore soon), and an A6-3400M llano laptop (stars die shrink). Piledriver is a worthy successor and an all around great upgrade for Ph II.

Yup, I agree the piledriver is significantly faster than Phenom II in some tasks, and the rest you can't notice a difference.

The point is that Vishera doesn't leave Thuban in the dust; it meanders in the same neighborhood, albeit a couple of blocks down the street. Both uarchs are good, but Vishera is absolutely not conclusively better.

The highest a Phenom II chip got on that benchmark was just north of 60fps (the main target of the benchmark) and that was a Thuban clocked as high as it could go. The highest AMD chip on that benchmark is a Vishera clocked as high as it could go, and it's in the 76~fps range. The entire point is to OC as high as you can go (while remaining stable, obviously) so you get the best performance you can with PCSX2. The difference in clocks can't be pushed aside for any inane reason just to downplay the advantage of Vishera.

So no, those benches don't help your case at all, and I'm not sure how you even came to that conclusion. The bench isn't like a PC game, 60fps = full speed since that's the refresh rate of the TV's (for NTSC-U/C and NTSC-J regions) the games were running on. An extra 17+fps is a huge deal, and you only get roughly 1.5fps per 100mhz with Phenom II. Vishera is slightly higher. Even the APU's leave Phenom II behind on that benchmark.

There are even PC gaming benchmarks where the Thubans trail behind Piledriver chips. So it's not in the "same neighborhood" or anything at all.

nope. think you're confused. the Phenom 1 & 2 family are k10

as for equivalency... generally speaking you need to clock your 6 core piledriver about 15% higher then your 6 core thuban to land the same frame-rates and benching performance numbers. 15% might not sound like much but when we're sitting at 4.0ghz it's 600mhz... so a 1100T at 4.0ghz will run about as fast as a fx6300 at 4.6ghz... a 1100T at 4.2ghz (generally on average it topped out around here) would be equal to a fx6300 at 4.83ghz (which is ironically enough the average top end overclock for the fx6300 too). in my mind the two chips are basically equal. at least close enough if i were the owner of a PhII x6 1100T i wouldn't see a move to a fx6300 as a step up, just an excuse to spend more money... and I'd see a move to an fx8350 as just a trade for MOAR CORZ.

This doesn't mean piledriver isn't faster, or won't be faster then Thuban. frankly if i had any other thuban i'd probably see a move to piledriver as a step up... mostly because except for the 1100t they overclocked like crap. But if i was sitting on a 1100T i probably wouldn't bother with the swap unless mine didn't overclock well.
