AMD preparing 5GHZ CPU?

[tajoh111]

Stilt: I think it could be C1 revision with better power consumption. But it is only theory. I know, i have one FX-6300 low VID, he reached over 4950 MHz at 1.44V in load, but it is very hot chip after OC, because Δ voltage offset is the same as some middle VID chip with 1.5V in load. But if is it price around 750 dollars after that I hope for some bundle with AMD FX liquid cooler or something else.

Making a chip that requires liquid cooling, massive volts(and massive power) to reach reach the desired speed is a pretty hollow victory. This would basically be a publicity stunt which highlights the inefficiency of bulldozer more than the performance prowess of it. Such a solution shouldn't be coming from AMD as it makes them kind of look bad.

Reviews would show a chip that beats Intel in multithreaded loads, loses in single, while consuming 2-3 times the power.

AMD did something in the past as stupid as this could be. Its called the 4x4 platform, pretty much a marketing stunt.

Even assuming that such a product sees the light of day, think just on the pros and cons of it for a second: The only pro is its nominal performance. For con, take for granted its power consumption, price from both the Processor itself and more expensive high end Motherboards with official support for it, very possibily noise due to the heavy duty Fan that should be used assuming air cooling, and the non existant overclocking margin because the dies are near the absolute limit of what the architecture and process node can give.
Assuming all that, wouldn't you think that you can instead use that money to buy a Ivy Bridge series K Processor, an aftermarket heatsink, and overclock it enough to attain the same level of performance? Chances are that is both cheaper and MUCH more power efficient than whatever you could get from a Vishera.

The inclusion of a $50 closed loop cooler and an Operation Scorpius comic book would make the $800 price for a $200 chip seem like a better deal.

tajoh111: if you are fan and enthusiast, dont care about price/performance/power ratio...If you are not enthusiast always you are be focused for different segment. Look at cars, awesome cars are not often cars with the best speed or with the lower fuel consumption. But it must be love, interest, original...

there is example of car price/ratio/low fuel consum.


awesome speed car>



good car with higher fuel consum, but still original and interesting


All cars find your customers...

if those 8 cores of Vishera can reach 8.5K or even 9K , why do not buy them to break New World Record ? if you say AMD should sell at 200$, i must say "Please Leave Forum Because it's Xtreme System"

title of Thread is wrong , should be "AMD Works on Next TWKR Chip Based on Vishera"

95w AMD FX-8300 Piledriver
C0 Stepping
Base Freq: 3.3GHz
Turbo Freq: 4.2GHz

No where to be found at retail, except in OEM rigs from Asus and HP.

Buy me one, and I'll volunteer free rigorous testing.

Folks this RUMOR is being discussed in another thread here.

*** Spam Link removed ***

As far as AMD, FX sales have been excellent and for good reason because Vishera delivers excellent performance at a wonderful price. FX-8350's routinely OC P95 stable @ 4.6 GHz.-4.8 GHz. I do not see a 5.0 GHz. Vishera based CPU being good value @ $795. however. If AMD were to sell these at this price or similar, they would be for bragging rights only similar to the way over-priced, under-performing $1000. Intel CPUs.

The AMD CPUs of late make me think of other cars, Flank3r:

Bad Vishera?










I dont think so...And these are practice, not theoretical benchmarks

PS:I have feeling people hear about superpi only and not about real programs in 21st century. I like superpi as benchmark in overclocker league, but I know, this benchmark tell nothing about real performance today.

Ran some numbers thru CFD to see what kind of a heatsink is required to dissipate 180W of heat (@ 38.0 celsius).

The measurements are based on maximum allowed (official) numbers.

No doubt the heatsink could be improved by different design and materials, however the specifications would roughly be something like this:

Width: 92mm (AM3 max)
Length(1): 77mm (AM3 max)
Length(2): 92mm (spec exceeded by 15mm)
Height: 99mm (spec exceeded by 62mm with x25mm fan)
Gross Weight: 903.28g (excl. fan)

Length(1) = 0-49mm (H), Length(2) = 49-99mm (H).

Fin material: Aluminum Alloy (6063)
Number of fins: 37
Fin thickness: 1.1mm
Air gap: 1.42mm

Base: OFHC Copper (vapor chamber)
Base thickness: 8.0mm

Fan specification
Model: Delta Electronics AFB0912SH
Size: 92x92x25.4mm
Power: 9W (0.75A / 12V)
Flow: 102.59CFM @ 0.986 mmHg
RPM: 4800
Noise: 53dB(A)

Fluid Upstream Velocity: 2.61m/s
Fluid Fin Velocity: 4.87m/s

TCaseMax = 65.0 celsius
TAmbient = 38.0 celsius (max for 140W TDP)
TDelta = 27.0 celsius

Sink hotspot: 53.2 celsius

TIL1 = 2.446016417662195 celsius (0.0135889800981233 C/W) - Thickness 250 microns
TIL2 = 0.8071493153121977 celsius (0.0044841628628455 C/W)
TIL3 = 0.45036592231188 celsius (0.0025020329017327 C/W) - Thickness 20 microns (X23-7783D)
TIL Total: 3.703531655286273 celsius (0.0205751758627015 C/W)

TIL = Thermal Interface Loss

Die temperature: 56.9 celsius

Heatsink RTH (C/W): 0.105

This will make a collectible item "cpu' just like the Asus Ares video cards , I really like AMD idea

[lutjens]

It's a pity that Intel doesn't follow suit and release a special edition chip of their own...say Ivy Bridge-E, with all cores and cache enabled, fully unlocked and capable of 2P operation...

I have a feeling this chip is real
A little birdie told me this chip is coming !
Just hope these clock really well on some ln2
