In 2010, the ATI Radeon HD 4250 video accelerator was officially introduced to the market of computer components by the manufacturer. The technical specifications of this device at that time were classified as the least productive solutions. Therefore, such an adapter could only be found in the least productive computing systems. Moreover, such an accelerator was found both as a part of desktop systems and laptops.
Types of Accelerators
The characteristics of the ATI Radeon HD 4250, as previously noted, made it possible to use both in economy-class laptops and in budget system units. That is, there were two types of accelerators of this model. One of them was part of the AMD 880G chipset and was successfully used in desktop PCs. At the same time, the algorithms of its functioning were aimed at fulfilling the tasks with the maximum level of performance.
The second modification of the accelerator with this designation was used in laptops. In this case, the technical characteristics of the device were identical to that which was successfully used as part of desktop computing systems. The only difference was that the frequency of such devices was artificially reduced. Due to this, the autonomy of the laptop increased.
Desktop solutions
The characteristics of the ATI Radeon HD 4250 graphics card for the desktop system indicated that it was based on a microprocessor with the code designation RS880. It was manufactured according to 55nm technological standards and included 40 stream modules for processing graphic information. In addition to them, the RS880 was equipped with 4 rasterization units. The maximum clock frequency of this chip was 500 MHz. In idle mode, its value automatically decreased to 157 MHz.
This ATI Radeon graphics card uses part of the computer system RAM in the process. Moreover, the largest amount of addressable RAM is limited to 1 GB. The last value is set manually in the BIOS of the computing system.
The advantages of this accelerator model include the excellent overclocking potential of this microprocessor. From the nominal 500 MHz, its frequency can be increased without any problems to 900 MHz. In the 3DMark'06 test package, such a manipulation allows you to increase the result of this accelerator from 1832 points to 2241 points. Again, turning this integrated accelerator into a full-fledged gaming solution does not work out under any circumstances for the reason that it has insufficient speed.
Mobile PCs
In turn, the characteristics of the ATI Mobility Radeon HD 4250 are almost in no way inferior to the specifications of the integrated accelerator for desktop systems. It is based on the same RS880 chip, which is renamed the RV620. This semiconductor device has the same 40 GPUs. Even the frequency of these elements of the graphics subsystem in the nominal mode is 500 MHz. But, again, in the case of battery operation, its value will be artificially lowered by software algorithms in order to increase battery life. There are also 4 rasterization blocks in this chip. They operate at the same frequency as the rest of the graphics accelerator. Also, to store the processed information, this adapter uses part of the system RAM. As in the case of desktop systems, the amount of RAM used is set in the BIOS of the mobile computer. That is, the performance of this device is almost comparable to the speed of an integrated accelerator for desktop systems.
Reviews
The ATI Radeon HD 4250 specs focus on two of its significant drawbacks. One of them is low productivity, which allows only the implementation of the least demanding software tasks. And the second is outdated architecture. The advantages of this accelerator in any design include low cost and an acceptable level of energy efficiency even by today's standards. This is exactly how such an adapter is now characterized by the owners in their reviews on the corresponding resources on the global web.
Conclusion
The characteristics of the ATI Radeon HD 4250 were reviewed as part of this article. Both for mobile execution and for desktop systems. This adapter initially had low speed and allowed to solve only the simplest tasks. He can process similar software now.
