Add that i7 920 can do +2 bins or, max 2.93GHz with single core operation.
Really? I thought tb works on all cores same way. So no more tb inpact in single threaded operations.
The maximum TB available on an i7 processor will be dependent upon the processor and max multi stored in an MSR register, from Intel's whitepaper
Quote:
On Intel® Core i7 processors: Bits 31:24 of this MSR contain the max ratio with 4 active cores, bits 23:16 of this MSR contain the max ratio with 3 active cores, bits 15:8 of this MSR contain the max ratio with 2 active cores and bits 7:0 contain the max ratio with 1 active core. This ratio needs to be multiplied by bus clock frequency (BCLK) to get the actual frequency. The standard bus clock frequency is 133.33 MHz.
For a Core i7 965 -- I know the MSR sets max multiplier of x2 for 1 or 2 cores actives and a multiplier of x1 for 3 or 4 cores active. I am not certain about the MSR values for an i920, as I don't have one.
But I have ran tests skewing the clock/multipliers on the 965 and Anand tech's data on the i920 appears to be able to x2 with all 4 cores active (i.e. I can reproduce is numbers at a multiplier x2 over stock).
SAN JOSE, Calif. -- A rebound in chip sales for the second quarter has caused a major change in the overall IC rankings in the period, according to IC Insights Inc. (See rankings table).
In terms of sales in the second quarter, the ''climbers'' in the IC rankings included Hynix, MediaTek and TSMC. The ''descenders'' in the rankings included AMD, Freescale and Fujitsu, according to IC Insights.
Intel remained in first place in the rankings, followed in order by Samsung, Toshiba and TI, according to the firm. Thanks to a strong quarter, TSMC jumped from 10th to fifth place in the rankings.
ST was in sixth place, followed by Qualcomm, Renesas, and Sony. Hynix jumped from 13th to 10th place. Another ''climber'' in the rankings, MediaTek, joined the top 20 ranking by jumping six positions in 1Q09.
Among the ''descenders'' was AMD. The company fell out of the top 10 rankings. ''The second-largest MPU supplier in the world has continued to find that it is no fun to be in competition with the giant Intel,'' according to the firm.
Good thing AMD/GF don't stand alone but rather are backed by
the semi superpower IBM. Oh wait, so-called big blue doesn't
even make the list. :-P

Huh? All the desktop Bloomfield processors are +1 for quad and +2 for single.
For the second quarter, AMD's market share slipped from 20.9 percent to 18.7 percent, slightly lower than the 18.8 percent share the firm recorded in the second quarter of 2008. Intel, meanwhile, saw its share increase from 80.0 percent a year ago to 80.5 percent, up from 78.2 percent during the first quarter of 2009.

Oh, wait -- why is this a good thing, again?
Never said it was, simply bringing forth more evidence refuting the original post of this thread.
Oh, sorry, I guess I just misread the glee with which you seem to always bring up negative news for AMD (or Sun, or IBM).
I can see why it's so important to provide yet more evidence contradicting a comment regarding a story written over three months ago about market share changes six months ago while actually agreeing with the figures stated in said story.

Well I have to admit to some degree of enjoyment to doing this but it
has nothing to do with being unaware or indifferent to the fate of the
honest hard working engineers at tech companies that fail to compete
because of incompetent management or obsolete business models,
nor do I have any desire for less competition.
Simply put, it is quite satisfying to deliver a two by four of timely reality
upside the head of whack-job fanboys of such companies.
If you don't like it then feel free to not read my posts.
SANTA CLARA, Calif.--(BUSINESS WIRE)--As a result of stronger than expected demand for microprocessors and chipsets, Intel Corporation now expects revenue for the third quarter to be $9.0 billion, plus or minus $200 million, as compared to the previous range of $8.5 billion, plus or minus $400 million. The gross margin percentage for the third quarter is expected to be in the upper half of the previous range of 53 percent, plus or minus two percentage points. All other expectations are unchanged.
Can AMD keep up with Intel as it accelerates out of the downturn or will it continue to lose market share as well as money?

as an ex AMD employee I have to completely agree with you on this one.
