Purported AMD Bulldozer Benchmarks Leaked Reported by
Sub on Monday, July 11 2011 2:37 pm
DonanimHaber have run an AMD FX engineering sample through a battery of
tests. The engineering sample is said to be a B1 stepping chip clocked
at 3.2 GHz. The Turbo Core 2.0 can up the clock speed up to 3.6 GHz with
all cores active, or a whopping 4.2 GHz with only 50% (i.e. 4 cores)
active. Needless to say, these are likely not the final shipping clock
speeds.

The sample features 2MB L2 cache per module, for a total of 8MB and 8MB
L3 cache shared between all modules (and cores). The motherboard used
was a Gigabye 990FXA-UD5, a high end 990 FX motherboard. The GPU paired
is a GeForce GTX 580. We have compiled a table of the benchmarks as
reported by DonanimHaber.
| Benchmark | Score |
| 3DMark11 | P6265 |
| Fritz Chess | 29.58, 14197 kn/sec |
| PCMark 7 | 3045 |
| Cinebench R10 | 24434 |
| X264 | 45.39 fps (P2), 136.29 (P1) |
In addition, it took 19.5 seconds to complete SuperPi 1M, which is much
slower than Intel competition. However, in real world benchmarks, the
story is rather different. In X264 Pass 1 the Bulldozer sample
(henceforth mentioned as simply "BD") results a whopping 136.29 fps. To
put this in perspective, Intel's fastest CPUs can only manage ~100 fps.
However, it is always Pass 2 that is the real test. BD completes with
45.39 fps. The typical speed for a Core i7 2600K is ~36 fps, while
Intel's 12-thread goliaths complete in the ~47 fps range. BD is clearly
far superior to the 8-thread Sandy Bridge, while nearly catching up to
the Gulftown champions.
Even more impressive is the 3D Mark 11. While this score depends from
platform to platform, when coupled with a GTX 580, the previous 3D Mark
11 champ Core i7 2600K struggles to achieve the P6000 mark, typically.
BD easily sails by with P6265. In Fritz Chess, BD overpowers Core i7
2600K yet again, with a score of 14197 kn/sec. However, it falls short
of Gulftown CPUs, which are typically in the 17000-18000 range. Finaly,
in Cinebench R10, BD returns a score of 24434. With this score, it slots
right in between Core i7 2600K and Core i7 990X.
The results are consistent, for the most part. In multi-threaded
applications, BD significantly outperforms Core i7 2600K, and almost
catches up with 6-core Gulftown. In less muti-threaded applications,
like 3D Mark 11 or X264 Pass 1, thanks to an incredible 1 GHz Turbo
Core, BD overtakes Gulftown CPUs. In all situations, BD ended up well
ahead of Core i7 2600K. In every situation, BD was massively faster than
Phenom II X6 1100T - more than 50% in many cases.
Of course, these benchmarks and comparisons should be taken with a grain
of salt - especially it being an engineering sample. If previous
rumours of stock clocks up to 3.8 GHz and a price tag of only $320 are
true, AMD could have a real winner on their hands. Even with the
engineering sample's clock of 3.2 GHz, a $320 is a bargain for a CPU of
this power, wiping floors with the mighty and similarly priced Core i7
2600K. Having been delayed, FX-Series CPUs are now expected to release
for desktops in the late August / early September timeline, with more
information expected in the coming weeks.
