The tests performed by the specialized media confirmed that this is the most powerful chip company in the consumer range, except for the Phenom II TWKR for obvious reasons, a special product that is not for sale. Features that bind to their ability to overclock (stable at 4 GHz without special cooling) and its compatibility with plates already on the market with DDR2, DDR3. The conclusions highlight that the 965 is highly competitive, not more faster than the more powerful Core i7, but is very close in most of the tests at a lower price. Thus, today’s Phenom II X4 965 BE introduction is actually a fairly important one for AMD. On one hand, it could earn the company its mainstream performance crown—at least for a few weeks. On the other, it could be the last time Phenom II looks as competitive as it does now. Of course, that’s going to depend mightily on how the upcoming Intel chips perform.
Up Against Core i5
Of course, we’re not able to publish performance numbers with the pre-production Core i5 processors currently running in the lab, so it’s hard to officially quantify how Phenom II will size up. But we can make best guesses using today’s Core i7s as rough test subjects.
You’ll find all of our usual benchmarks on the pages that follow. First, however, we wanted to set up Phenom II X4 965 BE against a hypothetical Core i5-750—a processor expected to cost less than $200 when it launches. We simulated the 2.66 GHz offering with a Core i7-920, which runs at the same clock rate. Of course, we had to pull out a single channel of memory (yielding two channels of DDR3-1333) and disable Hyper-Threading, since Core i5 won’t have that feature. The one variable we couldn’t reproduce was Core i5’s enhanced Turbo Boost, which is expected to accelerate clocks to 3.2 GHz when a single core is active. Core i7-920 only benefits from a single bin of Turbo Boost, yielding 2.8 GHz instead. The only other platform capability setting LGA 1156 apart from LGA 1366 is the use of on-die PCI Express 2.0, which we’ve tested extensively and can say that, in single-card configurations, has almost zero impact on performance versus the X58’s chipset-based connectivity.
As we've already mentioned, the Phenom II X4 965 Black Edition is an update to a familiar design. In fact, AMD readily admits that the silicon belongs to the same revision used to enable its Phenom II X4 955 Black Edition, running at 3.2 GHz. To that end, it centers on a 45nm manufacturing process, it features a 6MB L3 cache, boasts Cool'n'Quiet 3.0 technology, and better branch prediction than the first-generation Phenom family. Like its predecessors, the Phenom II X4 965 sports 64KB of L1 data and instruction cache per core, plus 512KB L2 cache per core, to complement the shared L3. An integrated 128-bit DDR2/DDR3 memory controller (running at 2 GHz by default) interfaces with a pair of 64-bit channels. If you're using the X4 965 on an AM2+ motherboard, speeds of up to DDR2-1066 are officially available. If you're using it on an AM3 platform, you can install DDR3-1333, though it should be noted that only one module per channel works at that frequency. And whereas AMD shipped its Phenom II X4 940 with a 1,800 MHz HyperTransport link, the X4 965 accelerates that to 2 GHz--just like the X4 955 before it. The chip's nominal voltage range is .825V-1.425V, so we won't be surprised if power consumption falls within the previous flagship's ballpark. Because it runs at 3.4 GHz, however, AMD is rating the X4 965 at 140W instead of the 125W used in previous flagship Phenom IIs.
Overclocking
The primary advantage of the new processor stepping – lower heat dissipation – should in fact tell on the frequency potential growth. To check this assumption we performed a few traditional overclocking experiments. We used a system built around Gigabyte MA790XT-UD4P mainboard and used a Thermalright Ultra-120 Extreme processor air cooler with an Enermax Magma fan installed on it.
Since Phenom II X4 965 processor we are talking about today belongs to the Black Edition series we decided to overclock it in the most natural way in this particular situation: by raising its clock frequency multiplier. At the same time I would like to remind you that as we have already seen many times before, the alternative approach using increased clock generator frequency is just as efficient.
Speaking of the overclocking results I would like to say that the CPU with new processor stepping did in fact demonstrate higher frequency potential. I would like to remind you that during the first Phenom II X4 965 C2 processor stepping tests we could get the CPU to work stably only when we increased its clock frequency from the default 3.4 to 4,0 GHz. With the new Phenom II X4 965 the overclocking with an air cooler was immediately increased by 200 MHz, (205X19.5)

setting the bios
We are faced with a bios that continues with the style that GIGABYTE has used recently. As usual in this brand several bios options are hidden, and we should press "Ctrl + F1" to qualify for them. Among the hidden features can be found, inter alia, the ACC as recently brought, or Advanced Clock Calibration, which has allowed unlock the fourth trinucleo core processors in some of the green flag. Among the options that will enable the overclock you have everything that we need. Highlight the memory multiplier, which in this case allow us to configure the memory up to 1600 Mhz (not the 1666 + we've seen screen-printed on the board near the ports of memory), speed far exceeding the 1333 MHz for which supports AMD processors. Highlighting the fact that along with the options to find information set voltages and speeds we are configuring end, data that will be very useful, very convenient and saves you from remembering walking or taking out the calculator.
Timmings configuration contains more options than almost anyone is capable of knowing, so we have total control over the reports. Also in this submenu are again setting the FSB and memory multiplier, so that within this submenu have all that we need to configure memory, with the exception of the voltages. It also informs us of the SPD settings and the settings that will be used if we leave everything on Auto. Perhaps the only downside is traced back to this menu to configure a timming that we must manually configure all, not be possible to leave some in "Auto". The option of "bargain" Unganged "is hidden by not pressing" Ctrl + F1 "and we will need if we are to maintain dual channel over 1333Mhz. Another feature of this bios can not forget is the information that gives us the bios on the right side of the screen on the option you have selected. It is normal that the bios give us some information about the parameters that we try to manage, but in this case was a pleasant surprise and very much to offer úti Once we configured the bios, will be spent on custom prime for at least twelve hours. Then pass the test benches and bench to see the overclocking performance of our audit. I recommend having the HT link multiplier to x7 and x8 multiplier = 1800Mhz NB, since turning down synchronously the NB HT Link and performance is not adequate. But special attention to the HT link, since it is always better to have X7 or down depending on clock frequency. Regarding the voltage, the default Vcore of the processor is 1,350. I've adjusted at 1.50 the vocre 1.550 the VcpuidNB 1,550, NB SB +0.2 to +0.2 ram 1.65 and the thermal solution of the review are stable at 4000MHz. With exceptional performance relative to the price we paid for the processor. 155 € Deneb 965 rev. c3
Conclusion
As for the new AMD Phenom II X4 965 processors on the new core stepping introduced today we can certainly recommend them to those computer enthusiasts that have good reasons to go with Socket AM2/AM3 platform. The CPUs with new processor stepping will definitely be better than their predecessors. However, it is important to remember that top quad-core AMD processors are currently a pretty weak offering against the background of their competitors. In fact, they can only compete against the old similarly priced LGA775 CPUs and only in terms of nominal mode performance. Fortunately, we can conclude that the results provide a processor with a ópitmo performance and value for money which is very interesting. With the i5 intel core market remains the midrange processors offer a high rendmiento, but the performance difference on the price, this phenom makes an interesting option for enthusiasts gammers.
