ARM Unveils the Cortex-A72 Processor Architecture Details

04/29/2015 - 12:17

On February 3rd, ARM announced a slew of new designs, including the Cortex A72.  Few details were shared with us, but what we learned was that it could potentially redefine power and performance in the ARM ecosystem.  Ryan was invited to London...

Improving Upon and Surpasing the Cortex-A57

04/29/2015 - 01:07

ARM is not disclosing every single improvement and optimization, but they have provided us with a few examples.  The first portion to get massaged is what we consider the Front-end. [inline:files/review/2015-04-28/front_end.jpg]

AMD Zen Diagram Leaked and Analysis

04/27/2015 - 18:06

There are some pretty breathless analysis of a single leaked block diagram that is supposedly from AMD.  This is one of the first indications of what the Zen architecture looks like from a CPU core standpoint.  The block diagram is very simple...

28 nm GPUs Extended Through 2015: 20 nm Planar a Bust

04/01/2015 - 11:27

We have been very spoiled throughout the years.  We likely did not realize exactly how spoiled we were until it became very obvious that the rate of process technology advances hit a virtual brick wall.  Every 18 to 24 months we were treated to...

28 nm Continued

04/01/2015 - 11:23

AMD still has not started fleshing out their entire refreshed line of parts.  The 300 series of cards have not seen the light of day, but the situation is becoming a little clearer every day.  AMD gave us a glimpse of the future when they...

Asus STRIX GTX 750 Ti Review: Quiet, Tiny, and Effective

02/26/2015 - 10:49

The last few weeks have been dominated by talk about the memory controller of the Maxwell based GTX 970.  There are some very strong opinions about that particular issue, and certainly NVIDIA was remiss on actually informing consumers about how it...

AMD Releases more Carrizo Details: AMD's ISSCC 2015 Presentation

02/23/2015 - 20:45

Some months back AMD introduced us to their “Carrizo” product.  Details were slim, but we learned that this would be another 28 nm part that has improved power efficiency over its predecessor.  It would be based on the new “...

Further Power Saving Mechanisms

02/23/2015 - 17:52

VAO, or “Voltage Adaptive Operation” was originally a technique introduced in Steamroller, but has been adapted for Carrizo.  It is common practice to apply more voltage to a CPU than is actually necessary, and this is done to prevent...

Conclusion

02/22/2015 - 20:58

I really enjoy working with budget cards.  I like to see what a user can get for the lowest possible amount, yet still be able to play modern games at reasonable frame rates and quality settings.  It is a challenge to get all of the compromises...

Power, Temperature, and Overclocking

02/22/2015 - 20:57

Power We finally come to the area where this particular board excels.  Maxwell was built from the ground up to be the most efficient architecture on the market in terms of power to performance.  When we take into consideration the performance...
