Processor
CB R11.5 multi start 2.5 GHz - CB R11.5 multi end 2.5 GHz

The Core i7-3537U (2x 2.0 GHz) is an ultra-low-voltage processor with a TDP of 17 watts. The clock speed can be increased up to 3.1 
GHz via Turbo Boost 2.0 (single-core load) but only if the generated heat can be dissipated. That is what we check with the 
Cinebench R11.5 under single- and multi-core load. The maximum theoretical clock speed is neither reached at the beginning nor the 
end of the benchmark: 2.5 GHz is still well above the standard speed though (no throttling).

Directly compared to the i5-4200U the 3537U loses clearly despite the higher clock speed. The built-in i7-3537U is by no means a 
slow model, however, the cooling system seems to be overwhelmed: The chart CPU Multi 64-bit shows that even the older i5-3317U is 20 
to 40% faster. The same goes for the single-core test: At least the 3317U improves by 20%. The Lenovo IdeaPad Yoga 13 is an 
exception and suffers under considerable CPU throttling.

To put it another way: The built-in Core i7 is a fraud because the overwhelmed cooling system limits the performance drastically. 
Asus might as well have simply installed a cheaper Core i5. We get more into detail about heat generation in the segment 
"Temperature".

Processor

The synthetic CPU-oriented benchmarks rank the Yoga about average with other Ultrabooks with the same CPU, if not a little lower. 
For example, the similarly equipped Spectre XT 13 and Samsung 530U3C Series 5 both score at least 10-20 percent higher than the 
Lenovo in CineBench 64 Bit CPU tests and the multi-core wPrime tests. This may be due to the poor Turbo Boost stamina of the 
processor in the Yoga as discussed in the stress test below.

Stress Test
Prime95 and FurMark were utilized to simulate stressed condition first independently and then simultaneously while monitoring 
CPU/GPU status with various tools.

We stressed the processor with Prime95 and noted any fluctuations in CPU speed. Under the High Performance setting, both cores idled 
at their advertised 2.4 GHz Turbo Boost speeds according to HWiNFO. This quickly dropped to a more stable 1800-1900 MHz range after 
initiating the benchmark, suggesting that the processor cannot sustain its Turbo Boost speed for even a considerable duration when 
under load.

The integrated GPU was then stressed with FurMark and monitored with GPU-Z. Similar to the CPU, the GPU Turbo Boost (1050 MHz) was 
only in effect for the first several seconds of the test and eventually leveled off at the 400-550 MHz range.

Under full stress from both Prime95 and FurMark, both CPU and GPU speeds were observed to be operating at their respective minimums 
of 800 MHz and 350 MHz. These speeds are essentially the idling states when in Power Saver mode. We ran 3DMark06 immediately 
following the stress test, which revealed a lower final score of 3206 points compared to the 4000+ points prior to the stress test. 
Throttling is thus a possibility under high enough workloads and conditions.

Processor

We began our processor test with the Maxon Cinebench suite. In the Cinebench R10 (64-bit) multiple CPU benchmark, the installed 
Intel Core i5-3317U scored 7991 points, putting it behind comparable configurations. Its performance was 14 percent behind the Dell 
Vostro 3360 and 16 percent behind the Asus Zenbook UX32VD. The previous generation Samsung Series 5 530U3B-A01DE remained 23 percent 
behind our test unit with 6138 points. The newer Cinebench R11.5 confirmed our previous results, showing the Dell Vostro to be 28 
percent faster than our test device. In this test, the previous model was 16 percent slower than our sample.

These poor results prompted us to take a closer look at the CPU’s Turbo Boost behavior during the Cinebench R11.5 tests. We observed 
that the processor clock dropped to the 1.7 GHz base clock, proving that Turbo Boost was not enabled. This might have been a 
consequence of the temperature issues mentioned in the Emissions section. We confirmed the absence of Turbo Boost under load using 
Cinebench R10. This absence puts the 530U3C-A01DE at a considerably disadvantage when compared to other ultrabooks.

Processor

The "U" in the description of the 1.7 GHz dual-core Intel Core i5-3317U CPU indicates low power consumption. The ULV processor uses 
lower voltage and hence consumes less power. This particular CPU is frequently used in tablets and Ultrabooks.

The results of the synthetic Cinebench benchmark tests shows that the performance of the Samsung ATIV Smart PC clearly lags behind 
other competitors with the same CPU: the Toshiba Satellite U920t-100 managed to score at least twice as many points. Only the 
Fujitsu Stylistic Q702 performs on the same level since its processor was hampered by massive throttling.

It is in fact throttling which is the reason for the uninspiring performance. The CPU never managed to exceed 1.2 GHz regardless of 
which power profile we had activated or how many cores were utilized.
