Since I am still waiting for the writeup from Toms on the 750K, I decided to translate this writeup that I found on this processor and I figured I would post the Google translation here for others benefit.
The original article can be found at: BitsandChips (more 750K benchmarks can be found at iXBT Labs)
AMD Athlon X4 750K: Trinity continued to call
AMD, according to its own internal philosophy, which has ancient roots, at least in the field of semiconductors, poses as a main feature of its products, the price / performance ratio. And 'period from the foundation that is so, and still keeps this standard.
As for the Trinity, even for the 750K looks can be deceiving
The Athlon X4 750K ago part of such a category of products. E 'a CPU with a very competitive price, equal to 70 euro approximately, and has which distinctive feature the multiplier unlocked. Never a CPU with such a low price, at least in the recent past, has had such a features help you. Perhaps only the Phenom II 550, but at a slightly higher price point, 90 euro.
The 750K is a CPU based on Core Piledriver and belongs to the family of the Trinity APU. The however, has been cut away an important part, the iGPU. The Athlon X4 750K can not exploit a of the peculiar characteristics of the tabs mothers FM2, the doors video. E 'is then a classic CPU to which must be paired a discrete video card.
This has allowed AMD to be able to market the CPU at a great price basis, and at the same time, how we are going to observe, to make a small Best Buy, if you are looking for a product with a ridiculously low price, but by chance anything but modest.
Without linger more over we go to see how it behaves on the field.
The 750K has many features in common with the 5800K processor that we used for comparison. Because the Web is full of reviews of this APU (including ours) did not seem like the case of redo all the benchmark for comparison with other CPUs from Intel and AMD. Rather, we focused on the differences between these two products from AMD. Costing about 50 euro more, it is advisable compared to the 5800K 750K even if you must use a discrete video card? The 5800K is actually more handsome, or more likely overclocking, compared to 750K?
A10-5800K CPU Athlon X4 750K
Default Frequency 3800 MHz 3400 MHz
Turbo 4200 MHz 4000 MHz
TDP 100 Watt 100 Watt
The price would you give to understand this. Many will be inclined to believe that the 5800K must have a chip selected in-house, as opposed to 750K, the latter probably a gap of production. But is this true?

To test the potential of the two CPU configuration we used a FM2 enough thrust, made up of top grade components. We believe, however, that the same performance can be achieved with less expensive components, but more about that in the conclusions.
To run the tests on the CPU we have complied with the following rules:
On the card were installed only the necessary components: CPU, memory, video card and hard drive.
First of all let's start with what is probably the feature that most interested in those who are reading this article: the propensity of the two CPU overclocking.
By analyzing several reviews on the 5800K we found that the maximum frequency, stable, level is approximately 4400 MHz @ 1,475 v, do not overdo it with the overvolt, as you can see from the table below.
Site Frequency (MHz) vCore (Volt)
Anandtech 4400 1.45
TechPowerUp 4500 ?
Bit-Tech 4400 1.50
Legit Review 4600 1.50
Hardware Secrets 4500 1.50
Hardware Canucks 4770 1.60
PureOverclock 4900 1.65
eTeknix 4500 1,475
Our 750K, perhaps about the iGPU cut with a laser, is able to achieve much better results. Always with a voltage of 1,475 v the 750K manages to reach the frequency of 4800 MHz, making it perfectly stable. The 5800K in our possession can not reach the frequency of 4700 MHz, perfectly benchabile, with a higher voltage, equal to 1.550 v, always in line with the sites mentioned, but with a voltage of 1,475 v arrives, stable at 4400 MHz . Ben 400 MHz less than the 750K. We considered stable overclock a processor after a one-hour session with Prime95 in "In-place Large FFTs".
Another curiosity is the maximum frequency reached by the NB. A voltage of default, in overclocking, for the 750K is 2500 MHz, while for the 5800K is 2200 MHz
Since we had available only a sample of 750K we can not say if all these CPU overclocking are so inclined, but we can say that the 750K has proved a pleasant surprise.
Below the screen with the bios settings for the frequency of 4800 MHz, in case anyone is interested.
In Cinebench latency Ram has a minimal influence on the final result for the AMD architecture. As we have already observed in the past, what matters is simply the frequency of the CPU.
Comparing the various results, the 750K has a price / performance ratio really amazing when overclocked. With just 70 € you bring home a true champion. The NB to 2500 MHz from that little additional benefit to 750K compared to 5800K at constant frequency (approximately 0.01).
WinRar proves to be greedy MHz is of lower latencies, and the maximum frequency reached from 750K puts him at the top. Despite being a Quad Core, the 750K can not even look bad in front of the FX-8120 CPU, even overclocked.
SFIV proves a game capable of note is the difference in frequency of the CPU is the difference in the timings of the memories. The 750K is able to have a good advantage over the 5800K overclocked. The test was carried out at 1920x1080, settings to a minimum.
Latency and bandwidth of the RAM improves hand in hand with the increase in the frequency of the CPU. Note how the 750K passing from the default frequency in the 4.8 GHz @ best latency RAM by about 15% and the bandwidth of about 25%. Values, however mediocre. In another review we have shown how a simple Atom D2700 eclipse latencies APUs AMD's low-end, and with poor memories can also keep up to Trinity. If we then take a CPU designed more for a low-power, and for the benefits as well, such as the i5-3427U, we can say that the CTRL DDR3 AMD's APU is far from efficient.
The iGPU 5800K integrated into the play, in our opinion, a very important role in the results we had in overclocking. The 750K, due to its absence, manages to score much better results, especially from the point of view of consumption, through the use of a lower vCore.
The values were measured in Idle in Windows, with all the power saving options enabled. In configurations overclocked the C & Q was disabled.
The values in Full Load were measured during the execution of Cinebench 11.5, reporting the highest value reached.
In light of all this it is evident that the 750K, if you must create a configuration with a discrete video card, is the best solution with a platform FM2. Destroys all over the 5800K APU, costing nearly half. Sometimes it is not true the saying "the more cheap is expensive."
The results we have achieved with the MSI FM2-A85XA-G65 were also achieved with the Sapphire Pure Platinum A85XT, and do not doubt that very similar results, given the low vCore required, can be achieved even with lower end cards, such as the excellent FM2A85X AsRock Extreme4 (about 80 euro). Similarly, you could opt for a less extreme heatsink. With the BeQuiet! in object, during Cinebench 11.5, with the fans to 60% and the 750K overclocked not have exceeded 50 °.
The most frequently reached in overclocking than the 5800K, good fuel consumption and the low price of the Athlon X4 750K marketing make a great product for those who want to build a PC with good features on a shoestring budget (150 euro between CPU and mobo).
We bring some external examples, always bearing in mind that the reviews here are in hardware and testing methods different from ours. From this review of LegitReviews the FX-4100 is behind the 750K prestazionalmente in Cinebench 11.5, as well as consume much more. In this other review of Xbitlabs, the CPU based on Core FX Piledriver require a higher voltage compared to 750K. Hardware Canucks has obtained similar results but with lower voltages, but the FX-4300 does not show to advantage especially in Cinebench 11.5 spite of the L3 cache. At about 5GHz (1.5v vCore) produces a score of 4.23. Looking at these results, the 750K is to be preferred to the FX-4300, without any doubt, even in relation to price. The first costs 70 Euros, the second € 115.
We can say that AMD, with 750K, has produced a really good CPU, but pays the fact of being little publicized. Available in limited numbers at the eShop, and almost unknown to most people, the Athlon X4 750K currently remains a lack Must Have: how can we expect to have something missing from the market? This decision to AMD could read: the Athlon X4 750K has all the credentials to cannibalize FX CPU quad core and part of the hexa-core, sold at a higher price. Why take off with their own hands a slice of the profits?
AMD can not even remove from the market the FX CPU core and quad core exa to make room for 750K. The AM3 + socket will remain exclusive ground for the FX-8xxx. Why maintain this whole platform to a single CPU? A big problem for AMD. He produced a great CPU, but can not sell except in limited numbers. The harsh law of the market.

To run the tests on the CPU we have complied with the following rules:
On the card were installed only the necessary components: CPU, memory, video card and hard drive.
The hard drive has been formatted, were then installed the operating system, drivers for peripheral devices and, when necessary, were installed patches and updates.
Each test was repeated three times and, if the results of some tests are shown too far from average (high variance), the same test was again repeated, discarding the incorrect result.
At the end of each test session, the hard disk has been formatted.
Cinebench 11.5: test suite based on the multi-platform animation software CINEMA 4D used extensively by studios and production houses for 3D content creation. Thanks to it we can assess the performance of the CPU subsystem even if the influence of the chipset, memory and graphics card installed in the system can not be neglected. The software performs a rendering tests capable of soliciting one or all of the available processor cores.
