Looking back on the Gulftown architecture
Core i7-990X processor is based on an improved version designed Gulftown 6 core – absolutely the same architecture with -980X and -970. The chip is pushed slightly higher pulse, stable operation at default clock 3,46GHz and a maximum Turbo Boost 3,73GHz when only 1 operation processing flow.
At the time of launch, there is nothing to argue about the power of Gulftown: 32nm process, 12 threaded processor’s 6 … Combined with the X58 chipset, the duo who made many people to hunger.
For Gulftown, Intel decided to take advantage of 32nm process to increase the multiplier and cache, rather than add something integration. The 6 core processor is 12MB L3 cache appear. In other words, not architecturally different from Bloomfield Gulftown. Each core has 32KB L1 instruction cache, 32KB L1 data cache and 256KB L2 cache.
12MB L3 cache to work with general purpose for why Turbo Boost performance was also increased, by such an application if it’s only 1 treatment operators, it will monopolize the entire cache. According to Intel, there will be a few applications such as enhanced game performance. However, in reality we are difficult to measure this acceleration, by applications increasingly tended to exploit multi-core power, while the use of one’s application are often quite mild.
In addition to having more and 4MB L3 cache 2 cores, Gulftown also smaller imperial predecessors: 248 mm square compared to 263 mm square the size of Bloomfield. Number transistor (semiconductor) also increased from 731 million to 1.17 billion. Very impressive to know that the Core i7-990X has the same power consumption 130W processors like cloning Bloomfield. i7-9xx 4 core of Gulftown RAM controller completely nothing changes, designed to serve 3-channel DDR3-1066 memory.
One other notable addition is the AES-NI – Advanced encryption standard Intel-based hardware. Previously appeared on the Clarkdale Core i5 processor and no performances were impressed, but when it comes to a Core i7-980X, AES-NI has partially confirmed the value and potential of their . Naturally -990X will inherit it.
The test configuration
Test results
PCMark Vantage 1.0.2.0
In this test, representative’s 6 core Phenom II X6 from AMD proved disadvantage Core i7-2600K least 4 core and was outstripped by 46%, probably caused by the majority of the components of this benchmark take advantage of the power of four cores.
PCMark Vantage test case in, only one test to bring victory to the Gulftown: Communications suite – test requires more CPU resources the most.
Communications Test suite includes 4 components, and 4 require heavy multitasking. 3 of which are related to the AES encryption and decryption processing in the stream as data compression, web translation, security and transcoding audio Window … We can say this test provides plenty of benefits Gulftown that compared to Sandy Bridge chips, as they have the ability to support AES-NI.
However, the Core i7-2600K to provide bandwidth “hash” greater AES ( “hash” AES – encryption function and data security)
The score: 1-0 for the i7-2600K.
3Dmark11 1.0.1
2 Gulftown processor victory in the test button 3Dmark11, partly aided by a test of physical processors fully utilize the advantages 6 core and the test was superior in graphics processing.
In this test, Futuremark create a processing flow on each of the test character graphics, and a threading per core processing logic in the physical test (6 cores 12 threads equivalent to 6 physical cores and 12 core logic). The ability to handle multitasking better bring absolute victory for Gulftown in physical tests, while the remaining tests (including graphics) Gulftown and Sandy Bridgela performance equivalent. Phenom II X6 still last.
SiSoftware Sandra 2011
Looking holistically SiSoft Sandra, the apparent strength of the Core i7-990X. The test results of Arithmetic and Multimedia benchmark will mark the leading 2 processor Core i7 Extreme Edition.
Intel also made some significant improvements in the speed AES in Sandy Bridge. That’s why the Core i7-2600K help overcome both Gulftown 6 cores in this test. Not accelerated algorithms for “hash” of security, both 2 chip 6 core are not successful in the Core i7-2600K for completely failing in this test.

Content Creation
Software full advantage of the Core i7-990X the core logic. The results show the difference between sizeable the Core i7-2600K 4 core human and Gulftown.
Also, it seems the difference of -990X than predecessor -980X is not much.
At the same time, the processor Phenom II X6 1100T 240 USD with 6 cores Core i7-960 really well exceed $ 300 4 core 8 processing flow in this test.
Again i7-2600K processor with two outstrips Extreme Edition. -990X -980X Proved a bit more dominant.
Add a more convincing victory. Core i7-2600K again finished in 3rd place – still better than the Core i7-960 and elder processors 6 core from AMD.
Obviously, Adobe seems a bit biased when less interested in optimizing for AMD processors. Phenom II X6 results 1100T processor are both 4-core Intel to drop back quite far.
We can say, Photoshop Premiere Pro CS5 is an excellent application exploiting multithreading capabilities, helps the processor 6 cores 12 threads showing remarkable strength, proved commensurate with the cost of $ 1,000. However, the writer would like to open a little parenthesis marginalized – have a simple way of increasing speed and much less expensive than if you read interested in Adobe CS5: use an NVIDIA CUDA graphics card to support encryption.
After Effects CS5 can not continue to maintain the advantages of the Gulftown. Core i7-2600K jumped to the lead in this test. Also, the distance between the start and end positions are not terrible as before.
Results like After Effects, Core i7-2600K pass -980X -990X and though not much.
Cinebench for two conflicting results for the CPU and OpenGL rendering benchmark.
Synthesis entire sections: 1-3 for Gulftown.
Productivity
ABBYY FineReader 10 – character recognition applications. The test requires 111 pages of documents scanned to calculate the time – the job requires a lot of parallel processing threads. This is precisely the great advantage of two processor Extreme Edition Core i7-2600K when we give away more than ten seconds. Meanwhile, i7-960 and Phenom II X6 are lagging quite far.
Lame is a single-threaded tests, the Core i7-2600K is synonymous with higher clocks to 3,8GHz. Add to that the performance advantage of rate / high clock of Sandy Bridge, i7-990X absolutely no chance, though well up 3,73GHz Boost.
It is a single-threaded application, WinZip for similar results Lame. In fact in the context of the current multi-core, the use of single-threaded applications do not test seems very reasonable. Anyhow this is one of the applications we use every day.
Through this test, for sure you can recognize the advantages of this latest version of WinRAR: Using all 6 core, Core i7-990X occupies a leading position, finished the test in less than 1 minute . Although advantageous performance / clock, but this time the Core i7-2600K again on 4th, losing both i7-960. Pretty weird! Congestion phenomenon may have occurred elsewhere.
Order to be classified as old: Core i7-990X leading, -980X second -2600K -third, followed in fourth position -960, finally Phenom II X6.
In this set of tests, the writer noted both gladiators were scored. The score 2-4 in favor of Gulftown.
Media Encoding
A single-threaded benchmark again. There is nothing surprising about the most Core i7-2600K.
MainConcept 2.0 must also take advantage of the multithreading capabilities of Gulftown stronger than elsewhere, while i7-990X and -980X on top, but the gap with -2600K just a little bit. Core i7-960 and Phenom II X6 dropped back quite far.
HandBrake for results like MainConcept 2.0: Gulftown victory button. Synthesis of this test: again both -990X and -2600K same score. This gave -990X 3-5.
Overclocking
Compared to overclocking, three processor the Core i7-990X, -980X and -2600K have one thing in common and fair: they are open multiplier. However, two Gulftown chip has advantages over a bit when they default 133MHz BCLK, we just increase the multiplier also achieve a high pulse rate. Meanwhile, the Core i7-2600K with 100MHz BCLK default, and can not afford to pull up more than 105. However, its multiplier is quite “high”: 54
Intel equips its Gulftown processor heatsink DBX-B big burly comes to serve overclocking, while the Sandy Bridge chip only be “distributed” copper core radiator fan normal.
With radiator fan “affordable”, Core i7-2600K can reach 4GHz threshold, by this time the temperature is too hot: 80 degrees C. Switch MUX-120 heat sink, the situation improved significantly: chip hit the highest clocked at 4,3GHz default voltage. Thus, if you want really high i7-2600K overclocked, you will have to add a heat sink equipped with good variety costs about $ 50.
All the above results are at default voltage of the manufacturer. All three chips are capable of pulling up a lot more momentum if the power is increased. In this respect, both Sandy Bridge and Gulftown has its own strengths: i7-990X has 133MHz BCLK while -2600K have much larger multiplier.
