Nvidia GeForce GTX 650 Ti Revie
It’s been over six months since Nvidia launched its Kepler architecture and we’ve finally seen the GTX 600 series enter more affordable price brackets, delivering a greater value every step of the way. In August, the company shipped its GK104-based GeForce GTX 660 Ti for $300, which was about 13% slower than the $400 GTX 670 while being roughly 33% cheaper — an unmatched performance-to- price ratio at the time.
We watched a rerun of that episode only a few short weeks later when Nvidia elbowed its way into the sub-$300 market. The company’s GK106-based GTX 660 launched at $230, landing right between AMD’s mid-range offerings. In addition to being only 14% slower and 23% cheaper than the GTX 660 Ti, the GTX 660 offered more value than the Radeon HD 7870 while matching the 7850’s price-to-performance ratio.
Having attacked the mid-range and upper-end markets, Nvidia has its sights set on the sub-$200 range, unleashing its GTX 650 Ti. At $150, the new arrival is roughly 34% cheaper than last month’s GTX 660 and about 7% pricier than the Radeon HD 7770, which fetches around $140 depending on features and rebates.
Interestingly, the GTX 650 Ti is based on the same GK106 architecture as last month’s GTX 660, though the GPU in the former has been significantly downgraded. The GTX 650 Ti features one less SMX Unit, which results in 20% less CUDA Cores. In addition, it has 20% less TMUs, 33% less ROPs, and its memory bus has been cut from 192-bit to 128-bit, reducing the memory bandwidth 40% from 144.2GB/s to 86.4GB/s.
These drastic reductions have led many to question whether the GTX 650 Ti will actually be worth $150 because the sub-$200 market is still heavily populated with many competent previous-generation cards. If the new arrival flops, it will be the first disappointment of Nvidia’s Kepler lineup and to some degree, it will help secure AMD’s footing in the budget territory. Let’s see if the GTX 650 Ti sinks or swims…
Gigabyte GTX 650 Ti in Detail
Nvidia has provided pictures of the GTX 650 Ti reference board, which appears to be no longer than a PCI Express x16 slot and requires a single 6-pin PCIe power connector. What we have on hand, however, is quite different. Although the PCB of Gigabyte’s GeForce GTX 650 Ti (N65TOC-2GI) is also very short, its dual slot cooler pushes the card’s total length to 23.5cm, which is only slightly shorter than the GTX 660 Ti.
The GTX 650 Ti’s GPU has 768 CUDA cores (192 less than the GTX 660) meaning there are 4 SMX Units, the TAU count has been cut from the GTX 660’s 80 to 64, while the ROPs have been reduced from 24 to just 16.
The memory subsystem has also been downgraded compared to the GTX 660, which featured three 64-bit controllers for a 192-bit-wide bus. The GTX 650 Ti drops one controller, resulting in a 128-bit-wide bus.
Additionally, Nvidia’s specification sees the memory capacity halved from 2048MB to 1024MB, though Gigabyte has still outfitted its GTX 650 Ti with 2048MB of memory, which is clocked at Nvidia’s specified 1350MHz (5400MHz DDR) and therefore falls in line with the company’s spec for memory bandwidth at 86.4GB/s.
Nvidia’s spec for the base clock frequency is 925MHz, while boost clock has been disabled for the GTX 650 Ti. Gigabyte has overclocked the base clock to 1032MHz, a 12% increase over the standard clock speed.
What makes Gigabyte’s iteration unique is its WindForce 2X cooler, which employs dual 75mm ultra quiet PWM fans connected to a custom shroud. Under these fans is a massive heatsink that measures 20.5cm long, 8cm wide and 1.5cm at its thickest. It also uses two 6mm-thick heatpipes for heat dissipation.
To feed the card enough juice, Nvidia calls for one 6-pin PCI Express power connector — identical to the HD 7850 and 7770. Nvidia also says those wishing to use a single GTX 650 Ti should have a 400 watt PSU or greater.
Unlike the GTX 660, the GTX 650 Ti doesn’t support SLI, so there is no connector on the top of the card. The only ports are on the I/O panel where you’ll find a pair of dual-link DVI-I connectors, a single HDMI 1.4a port, and a VGA port. Note that the DisplayPort socket is absent from the Gigabyte GTX 650 Ti.

Chipset
Components on the motherboard which is mostly composed of two chips, north bridge and south bridge.
The main functions of the chipset is a set of data flow between components installed on the motherboard. Normally two chipsets on the motherboard itself has different tasks with each other.
On the north bridge chip is used to regulate the flow of data to and from the processor, AGP bus, and the system’s main memory. Meanwhile, the south bridge chip that controls the flow of data from input output devices, PCI bus, disk interfaces, and floppy, as well as other external devices. Since the north bridge chip is more vital than the south bridge works, I wonder if the chip is fitted heatsink, fan, or a combination heatsink and fan by the manufacturer.
AGP
Stands for Accelerated Graphics Port. Its function is to transmit data from the CPU to the graphics card without having to go through the main memory, so the data processing can be accelerated graphics. Another advantage is the ability to AGP execute texture maps directly from the main memory. Comes with a variety of tastes, today most motherboards include AGP 4X bus that works at a frequency of 266MHz. For now, the AGP port is used for installing a new graphics card which is actually faster than using the PCI bus. However, some recent motherboards already includes Pro AGP port that can be fitted with either a 4X AGP based graphics card or AGP based Pro itself.
Memory sockets
This socket is where to put the memory on the motherboard. Memory sockets have different forms for different types of memory. Most motherboards have slots as much as 3 or 4 pieces, depending on the chipset used. For SDRAM memory, DIMM sockets is a must-have 168 pin socket, while for the type of DDR memory, a socket is a socket 184 pin installed.
Processor socket
Is to place the processor. If the days of old, there are still other options besides socket system is the system slot. However, after the era of second generation PentiumIII, slot type is then abandoned because of the cost of production is more expensive than using a socket. For business this processor sockets, processor choose a motherboard with the right socket. Socket 370 for Intel PentiumIII and Celeron processors, socket A for AMD Athlon and Duron processors, and socket 423/478 for Pentium4 processor.
CMOS
Stands for Complementary Metal Oxide Semiconductor. Of the shape is visible, it is shaped component IC (integrated circuit) The function holds the BIOS settings and can even keep its settings for mendayainya batteries are still good.
External Device ports (serial, parallel, audio, USB)
Usually located in the rear position of the motherboard. Its function is as a means to provide input (input) and output (output) on a computer system. This current generation motherboards have also included a USB port for “dealing” with
Other peripherals such as printers, scanners, digital cameras, and other USB-based peripherals. In addition to the USB port, sometimes on some motherboards also included an Ethernet port to enter into the computer network. This kind of type that is not too much, but it is very helpful especially for use in small offices or cafes that have a minimal budget.
Power socket (power supply, fan)
Its function is to supply power to all the components that are connected to the motherboard.
Casing Connector
Serves to connect the button / switch and indicator on the chassis to the motherboard. On a Pentium 4-based motherboard, also included an additional connector port is 12 volts so that the processor can work.
IDE and Floppy Connector
Definitely have to know what its function, which is an interface that connects the hard drive and floppy disk to the motherboard. Current hard drive interface on the motherboard which is widely used IDE Ultra ATA/100 capable of delivering data transfer rates up to 100 MB / sec. Maxtor is developing a new interface that is Ultra ATA / 133. But until this anniversary edition finished writing, there is no new information that the interface is getting good response from other vendors. It is also important in determining the size of the motherboard is recognized.
There are several types of motherboard sizes, ranging from AT, ATX and micro ATX. These measures are called form factor. In general, motherboard-motherboard ATX is now using this technology. Motherboardmotherboard no standard class of type micro ATX, motherboard while mid end or high end mostly use the ATX form factor. Although the form factor is different, every innards motherboard has the same standardization, so that it only affects the size of the casing which option will be used.
Jun 12, 2013 | COMPUTER
Central controller that regulates the work of all the components attached to it.
Regulate the provision of electrical power on any PC component.
Data traffic are all regulated by the motherboard, ranging from the storage device (hard drive, CD-ROM), a data input device (keyboard, mouse, scanner), or a printer to print.
development Motherboard
In the late 1980s and during the 1990s, to the PC processor market dominated by Intel. there is
Starting late 90s and early 2000s, the conditions changed. Processor market is no longer so dependent on Intel, because their competitor, AMD, issued a K6-2 processor and Athlon are apparently able to compete with Intel-made processor.
And in the same year an industry producing Taiwanese chipset, VIA Technologies, also has been able to make a quality chipset and priced. The motherboard manufacturer is no longer dependent on Intel to design and make their motherboards, so the development of the technology and design of the motherboard has increased very rapidly.
Additionally, overclocking fever also contribute their role in the development of the motherboard. The motherboard manufacturers are competing to issue a motherboard that is designed to provide a high level of overclock, but still able to maintain system stability. Anyway, if there is a motherboard that can not be used to overclock the processor and the memory, the motherboard is almost certainly less marketable. multiple processors for PC companies, but their influence is far less than Intel. Besides the average processor made they still take Intel’s x86 design as well.
