Behind Intel Core I5 661

Information processor with 32 nm fabrication was circulated a few months ago. Now Intel has begun marketing the processor with 32 nm process development.

i5 661

Although it still bears the i5 Core, Core i5 661 (codename Clarkdale) which does not really have too many differences from the previous i5 using code name (code name) Lynnfield.Najvidljiviji difference i5 661 is a dual-core processor , while the i5 750 is a four-core processor (quad-core processor as well as others who joined in the line of processors bernamasandi Clarkdale). Moreover, this is the first processor to successfully integrate graphics processing into "home" processor. The rest is the same for both of Lynnfield and Clarkdale was built on the Nehalem architecture.

As you can see the physical appearance of the new process, IHS behind him there are two cores, which is the core processor and the other is the core graphics processor.

S graphics processors in the processor, indirectly, the number will decrease as processor core occupies the core graphics processor. But still have reliable performance, Intel Clarkdale ranks equip it with Hyper-Threading capabilities, and Turbo Boost (except Clarkdale "Junior", as i3 / without Turbo Boost and Pentium G6950, which also has the lowest L3 cache).

i5 661 that we tested here has its privileges. If you look at the table, Core i5 661 is the fastest graphics processor speed compared to his brother. It would also have an impact on the TDP is also higher among other Clarkdale processors.

own graphics processor is Intel GMA with DX10 support specifications that are similar to the GMA X4500 integrated in the Intel G41 chipset.

Here we do two kinds testova.Prvi pure testing core processor vs. Core i5 661 750 i5.Drugi integrated graphics performance between the Intel Core i5 661 vs G41.

As the operating system you are using Windows Vista Ultimate SP2. There is also our test applications:
- PCMark Vantage Pro 1.0.1.0
- Sisoft Sandra 2009 SP4
- 3 Expression Encoder 3.0.1332.0 (video coding)
- DBpowerAMP 13.3 (audio coding)
- Sysmark 2007 Preview 1:05 (image rendering)
- Cinebench R10 (3D content creation)
- 3DMark Vantage Pro 1.0.1 (pre-performance)
- STALKER: Clear Sky Benchmark (3D game)

PCMark Vantage Pro 1.0.1.0

* Description: PCMark Vantage most applications built using Windows Vista.Softver is divided into three apartments: PCMark Suite, Windows Vista Consumer Scenario Suites, and the HDD Suite. It is used in this test is the PCMark Suite which represents the entire system.

* Results:. Although Core i5 661 has a higher speed, it i5 750 is still at a disadvantage in the number of its core processor

Sisoft Sandra 2009 SP4

* Description: SiSoftware Sandra 2009 is a Windows-based system analizator.Proces benchmark tests were conducted to test the CPU arithmetic and multimedia side. Gauges are also found in a module called memory bandwidth choice. When executed, the memory bandwidth is measured in the Main memorije.Test bandwidth is divided into two, Integer and Float. For the record, this is a test of synthetic (not real applications), so it does not necessarily result in line with real applications ..

* Result: Same as in PCMark Vantage, i5 750 i5 661 is still superior to a theoretical test SiSoft Sandra

.

3 Expression Encoder 3.0.1332.0

* Description:. With this software, we convert the AVI video file with the extension wmv

* Results: In the video encoding test, Core i5 750 with four still benefit from its core. Performance differences go far enough.

CDex 3.13

* Description: Measuring the effect of converting audio processor

* Results: For the first time, we won i5 i5 661 750th Obviously, this conversion program is more important than the number of processor core speed.

Sysmark 2007 Preview 01:05

* Description: Software Test aimed at measuring the performance of the system. Tests carried out in real applications and usage models are popular and are considered to constitute the majority of users. Applications can use the Windows Media Encoder 9, Photoshop CS2, Word 2003, 3ds Max 8.0. 20 SYSmark 2007 Preview is divided into four usage scenarios, such as e-learning, video creation, office productivity and 3D modeling. Each shows the performance of the relevant usage scenarios. While the rating results show SYSmark 2007 Preview overall system performance.

* Results: showed that the superior core i5 661 750 i5 in some tests and finally got a faster processor in this test Sysmark 2007th Again, the i5 661 speeds seem much help in an application that is actually able to take advantage of multicore processors.

Cinebench R10

* Description: This software is based on CINEMA 4D - animation software that is widely used in studios and production houses in 3D content creation. Cinebench R10 test system performance in making 3D sadržaja.Test used is specific to the provision of using multi-core processors.

* Results: As expected, if the application can use multi-core capabilities for optimum i5 750 with four points ahead in the left front i5 661

.

3DMark Vantage Pro 1.0.1 (pre-performance)

* Description: Aims to assess the system performance for DirectX 10 3D games. 3DMark does not use in real applications (a real 3D game). However, this tool has a number of principles that help meet those goals. Here's integrated graphics core i5 661 was tested and compared with existing integrated graphics solution on the chipset.

* Results:. Values ​​obtained far enough difference, we suspect that this is because the system used (processor and memory) have an impact on the overall performance

STALKER: Clear Sky Benchmark

* Description: Test performance of 3D games officially released by the developers of this game. This benchmarking tool fully supports DX10.

* Results: Here we see a fairly significant difference in performance between the integrated graphics processor. Armed with greater speed, Intel GMA 661 Core i5 on graphics cards that have surpassed the G41.

Conclusion

From the results of tests, the processor core i5 661 is quite competitive compared to the i5 750th With a high clock speed and the ability to Hyper-Threading, the impact of the loss of 50% of the primary is not too large. The graphics processing capabilities are not yet reliable for serious gaming (although the speed is high enough), but more than enough for everyday use. Solutions integrated graphics processor is also an interesting added value now that the ranks of Clarkdale, the solution for all-in-one computing can be realized to be more concise.
