AMD A8-5500
For each variant Trinity 100W, AMD also
offers a more energy-efficient version with a 65W TDP. The A8-5500 is a more
economical counterpart of the A8-5600K. They are identical in all
specifications except for the clock rate of the executive core. The 65-watt A8
model clocks them at 3.2 GHz (3.7 GHz in turbo mode). The Radeon HD 7560D
graphics core like the A8-5600K and operates at 760 MHz frequency. Thus,
however odd it may seem, the 35% TDP reduction is enabled by lowering the clock
rate of the x86 core by only 200-400 MHz.

A8-5500
The A8-5500 normally works at 3.5Ghz. At
high loads, its speed reduced to 2.9GHz, though AMD did not make this fact present
in the specifications.
A8-500 was not a popular product targeting
the multiplier to overclock and its frequency is locked. Overclock x86 core,
graphics core and memory controller it can only be done by changing the pulse
frequency initiated.

AMD A8-5400K
Starting from the A6 series, the Trinity
family includes APUs with a greatly reduced x86 part. For example, the A6-5400K
model has only one Piledriver module with two x86 cores for integer operations
and one floating-point unit. The capacity of the shared L2 cache is reduced to
1 MB, too. So, the total amount of L2 cache in this APU is only one fourth of
the A10 and A8 APUs.
The graphics capabilities of this
modification Trinity are also be reduced as well. The built-in graphics core in
A6-5400K is called Radeon HD 7540D. Architecturally, it is exactly one half of
the Radeon HD 7660D available in the A10 series.

A8-5400K
The A6-5400K doesn’t look deficient in its
clock rates only. The graphics cores runs at a standard of 760 MHz while the
execution cores, at 3.6 GHz (3.8 GHz with Turbo Core technology). In contrast
to the quad-core APU Trinity , the A6-5400K can be easily accelerates to 3.8
GHz and keeps on going at that frequency continuously at high loads. But, like
every other APU Socket FM2, it slows down sometimes, to 3.2GHz, when making some
difficult computings.
Hard to say that overclockers would prefer
something like the A6-5400K but it comes with unlocked frequency multipliers.
We can only intended that this capability is meant to make it more competitive
with Pentium and Celeron processors from Intel which absolutely cannot be
overclocked at all. By the way, the A6-5400K is the only overclocker-friendly
Trinity with a TDP of 65W.

AMD A4-5300
The A6-5400K seems to be the ultimate
simplification of the original Trinity design, but the A4-5300 is even more
simple. This APU has a more much lower specifications. It only has a dual core
Piledriver module with a shared L2 cache and its clock rate is 3.4GHz. The
turbo mode boosts this clock rate by a mere 200 MHz, but the worst thing is the
maximum memory frequency the A4-5300 supports is DDR3-1600. It is not only an
official line in its specifications. If you try to increase the speed of DDR3
SDRAM above 1600 MHz, the APU will not start. Therefore, the A4-5300 is the
only APU that we have to benchmark with DDR3-1600 rather than with faster
DDR3-1867 SDRAM.
AMD has been even crueler about the
graphics core here. The combination in the A4-5300 is called Radeon HD 7480D,
runs at 723 MHz and has 127 shader processors. In other words, only two SIMD
engines are enabled in the A4-5300 out of the six available in the original
design. Fortunately, AMD did not turn off encoding technologiesin this junior
APU as Intel did, so the A4-5300 is quite suitable for multimedia applications,
especially as its actual heat dissipation should be very moderate, considering
its relatively low clock rates.
