TI OMAP5 5430 vs TI OMAP5 5432

February 16th, 2011 1 comment

The OMAP5 is Texas Instrument’s newest System on a Chip due for production late this year. In order to support various devices, there will be two versions of the OMAP5 hitting the market: the OMAP5 5430 and the OMAP5 5432.

The OMAP 5430 and the OMAP5 5432 share several basic features. Both are built on 28 nanometer technology and a low-power CMOS process. In both cases, the system-on-a-chip uses two of ARM’s newest processor, the CortexA15. Besides the CortexA15 processors, capable of speed up to 2 GHz each, the OMAPs include two ARM CortexM4 processors. Multi-core POWERVR SGX544-MPx graphics accelerators for 2D and 3D graphics enhance multimedia capabilities. According to specs revealed by the TI website, both OMAPs provide a 5x or greater increase in graphics performance over previous generations. Both the OMAP 5430 and 5432 support 2D video playback (1080p60) and 3D video performance (1080p30).

Beyond these specifications, the 5430 and 5432 differ in order to serve different markets. The OMAP5430 has been designed for area sensitive devices. Planned applications include Smartphones, tablet PCs, and other mobile multimedia devices. The 5432 is made for devices which are not as concerned about space. The 5430 is therefore more cost-effective, and is meant to be used in larger computers and other consumer multi media devices. The 5430 is 14mm by 14 mm square in order to support its mobile market. Its larger counterpart, the 5432, is a slightly larger 17mm x 17mm.

Memory capabilities differ between the two versions. The smaller 5430 supports 2xLPDDR2 memory, while the 5432 supports 2xDDR3/DDR3L memory.

Camera support varies slightly between the two systems as well. The 5430 supports 24 mega pixel image capture. The 5432 supports 20 mega pixel image capture. While the 5430 supports an impressive four cameras and four LCD displays concurrently, the 5432 supports three cameras and four simultaneous LCD displays.

For those who are concerned with peripheral support, TI’s website gives a list for each of the OMAPs. The 5430 is listed to support: UART (6x), HSIC (3x), SPI (4x), MIPI UniPort-M, MIPI LLI, HSI (2x). The 5432, with slight differences, is listed as supporting: UART (5x), HSIC (2x), SPI (3x), MIPI UniPortSM-M, MIPI LLI, HIS.

The OMAP 5430 and 5432 are both built for remarkable performance while saving space and power draw whenever possible. Whether operating in a Smartphone or a desktop computer, the OMAP5 generation looks to be quite impressive.

Texas Instrument’s OMAP 5 is a 28 nanometer system-on-a-chip (SoC) that has been announced for production in late 2011. Although this means consumers probably won’t get their hands on the corresponding smart phones until late 2012, there is much to be anticipated in the mean time.

A major component of the upgrade from OMAP 4 to OMAP 5 is, of course, the processor involved. The design of the OMAP 5 is quad-core, featuring 2 Cortex A15 cores and 2 Cortex M4 cores. TI is the first to officially license the Cortex A15, ARM’s most recently developed Eagle core. Not many details of the Cortex A15’s architecture have been released, but at speeds of up to 2GHz per core, a major leap in technology from OMAP 4’s Cortex A9s is to be expected. TI estimates the OMAP 5 will triple the speed of the OMAP 4 while reducing its power consumption by 60 percent.

According to TI, OMAP 5 will allow mobile devices to run multiple operating systems at a level rivaling that of PCs. ARM based chips are estimated to control 95 percent of the tablet PC market share, so they certainly should know something about PC performance. According to TI the OMAP 5 will provide the best multimedia and graphics performance in the mobile market.

Creating major buzz is OMAP 5’s ability to support gesture-based interfaces, similar to the new Xbox 360 Kinect system. As touch-less technology invades all walks of life, its influence on smart phones is inevitable. Imagine moving 3D objects around with a wiggle of your fingers. And yes, a 3D display is a part of the deal. No glasses required.

Technically speaking, there are two editions of the OMAP 5. The 5430, most likely for use in smart phones, is 14 mm square, with PoP dual-channel LPDDR2 memory support. The 5432, targeted for larger devices, is 17 mm square with BGA dual-channel DDR3/DDR3L memory.

Also a part of the OMAP 5 package are 2D and 3D video capability at 1080p. Add in the support of facial recognition, a 24 mega pixel (5430) or 20 mega pixel (5432) camera , typical Wi-Fi technology, and 4G connectivity, and you have a perfect storm of impressive technology. Perhaps more amazing is that all of this power actually fits into that 14 – 17 mm wide space.

TI has said that they are targeting the future of Windows and are currently in discussions with Microsoft. With decent competition from Qualcom, Samsung, and even N-vidia, the processing world is constantly requiring much from its participants. With the OMAP 5, it certainly seems that TI has delivered.

Intel Core i5-760 – 2.8 GHz Quad Core processor

February 5th, 2011 No comments

Intel Core i5-760 is a 2.8 GHz quad core processor intended for moderate to high end desktop computing. Though it does not support Hyperthreading, it does support Turbo Boost, a feature by which the frequency of the processor is increased for a short duration of time to increase its performance. The maximum Turbo Frequency of Core i5-760 is 3.33 GHz. The Core i5-760 comes with 8 MB of L3 Cache that intel calls Smart cache.

Built with 45 nm Lithography, Core i5-760 has a TDP rating of 95 Watts. The Core i5-760 does NOT come with integrated graphics controller.

Here are the key specifications of the Intel Core i5-760

Number of Cores – 4
Nominal Clock Frequency – 2.80 GHz
Turbo Frequency – 3.33 GHz
Level 3 Cache Memory – 8 MB
Integrated Graphics controller – NO
Max DDR3 memory speed – DDR3-1333

The Core i5-760 has integrated DDR3 memory controller, which makes the processor to memory communication fast by reducing the latency. The communication with the chipset is using fast differential DMI Bus.

Other notable feature include the support for the Intel Virtualization technology, which is helpful in case you are running multiple operating systems simultaneously.

Performance and Benchmarking

The core i5-760 improves upon the clock frequency of the core i5-750 ( a 2.66 GHz part) by 5.2%. We should therefore, expect a performance improvement of the order of 4% to 5% in Intel Core i5-760 with respect to the Core i5-750. The result points slightly better performance for the core i5-750 with respect to AMD’s quad core X4 965 ( 3.4 GHz part).

The Passmark CPU performance score for the core i5-750 stands at 3641. We may therefore expect the score to be of the order of 3790. By Comparison the Phenom ii X4 965 has a passmark score of 2950.

February 4th, 2011 1 comment

Intel core i7-2630qm and i7-2720qm are both Sandy Bridge processors. The main difference is the normal operating frequency – while the Intel core i7-2630qm has nominal core frequency of 2 GHz, the core i7-2720qm is clocked at 2.2 GHz.

However, there are other subtle differences that makes i7-2720qm better than the more popular core i7-2630qm. Here is a the list of three most important differences.

– The Max core Turbo frequency of the core i7-2630qm is 2.9 GHz while that of the core i7-2720qm is 3.3 GHz

– The max DDR3 frequency rating for the core i7-2630qm is DDR-1333 while the core i7-2720qm can support upto DDR3-1600. Theoretically, it will mean a through put of 25.6 GB/s in Core i7-2720qm as compared to 21.3 GB/s in core i7-2630qm.

– The other notable improvement in the core i7-2720qm comes in the form of the turbo frequency of the graphics section. While both the processors have base graphics clock frequency of 650 MHz, the core i7-2720qm has better 1.3 GHz turbo core frequency, as compared to 1.1 GHz for core i7-2630qm.

You with 200 MHz or 10% increase in the processor core frequency, you may expect an improvement of the order of 7 to 10% in the core i7-2720qm. The improvement may be more marked if the DDR1600 is used in conjunction with the the 2720qm.

So how much is the difference in the performance – Check out the core i7-2630qm vs i7-2720qm performance difference.

Here are some more differences.

– Intel core i7-2720qm has support for WiDI diplay – the core i7-2630qm doe has none.

– The core i7-2720qm has support for the Intel Virtualization Technology for Directed I/O (VT-d) while the core i7-2630qm has none.

– The core i7-2720qm supports Intel My WiFi Technology which core i7-2630qm does not.

– The core i702720qm has been listed with support for 4G WiMAX Wireless Technology
