Radeon HD 3000 Series

The Radeon HD 3000 series is a series of desktop graphics chips from AMD and successor of ATI Radeon HD 2000 series. This makes it the seventh -generation GPUs with the name ATI Radeon. All graphics processors of this series support pixel, geometry and vertex shader 4.1 after DirectX 10.1. The Radeon HD 4000 series is the successor to this series.

History

The Radeon HD 3000 series is based on the architecture of the HD 2000 series, however, some improvements have been made: The feature set has been expanded and now includes DirectX 10.1, also supports this series now PCI Express 2.0. To eliminate the criticism of the high power consumption in particular the HD 2900 series, ATI PowerPlay was integrated into the chip, which not only voltage and clock speeds lowers in idle mode, but also unneeded switches off parts of the chip, whereby even the RV670 based map at light loads compete with the Geforce 8 series low-end products.

To reach one hand under load competitive levels related to power consumption, on the other hand to obtain the smallest possible die area, AMD makes the graphics processing units (GPUs ) at TSMC since the end of 2007 in the 55 - nanometer process finished. This optical shrink so that the in-house 65 -nanometer SOI process was outdated, which was used for processors. It has been customary to manufacture GPUs rather in older methods, because the chips are usually more complex than the usual desktop CPUs and with older manufacturing processes yield higher rates are achieved due to the greater experience.

On 15 November 2007 AMD introduced first with the Radeon HD 3870 and HD 3850 dual graphics cards based on the RV670 before, which should replace the R600 derivatives ( Radeon HD 2900 ). In addition to the innovations of the series they offered compared to the R600 and the UVD video decoder. The memory interface has been reduced for the purpose of cost reduction of 512 bits to 256 bits, in turn, the memory controller has been optimized for the reduced memory bandwidth remains sufficient for the GPU performance. The RV670 replaces the last still made ​​the 500 series GPU, the RV570 since X1950 Pro can be offered by him newer graphics cards based on the RV670 in the price region of the Radeon. Some board partners AMD brought in February 2008, the Radeon HD 3690 and 3830 for the Chinese market out, where it is modified variant of the Radeon HD 3850, at which reduces the memory interface to 128 bits and the UVD video decoder was partially disabled. The cards are not officially out of AMD.

The introduction of the Radeon HD 3650, HD 3470 and HD 3450 on January 23, 2008. These models are based on the RV635 ( Radeon HD 3650 ) and RV620 ( Radeon HD 3450/3470 ) and had the first graphics cards a port for the connection standard DisplayPort. The Radeon HD 3400 - series models also support Hybrid CrossFire technology, which brings the Radeon HD 34xx graphics card with the built- in AMD 780G and AMD 790GX Chipset Graphics higher performance. These models also have the optimizations that were introduced with the RV670, compared to the previous series, the sizes of the memory interface were retained.

In March 2008, the chipsets of AMD 780 series were finally introduced, which is a based on the Radeon HD 34xx, include integrated graphics solutions with the names Radeon HD 3100 ( AMD 780V ) and Radeon HD 3200 ( AMD 780G ). The latter IGP contains a unified video decoder which decodes high-definition video and others in hardware and thus relieves the CPU as opposed to the Radeon HD 3100. Also missing the HD 3100 already mentioned Hybrid Crossfire technology and digital monitor outputs.

In August of 2008, the range of the integrated GPUs to the was integrated into the new AMD 790GX chipset, enhanced HD 3300 graphics core, which is connected to the HD 3200 is identical, but has a higher 200 MHz core clock.

Manufacturers, which obstruct AMD chipsets with an integrated HD 3xxx graphics, have the ability to the graphics core to provide a private, Side Port said memory aside. This reduces the load on the system RAM by the graphics processor and can be triggered faster also. Size, memory technology, clock frequency and the width of the memory interface this side ports can be determined from the motherboard manufacturer and thus vary.

Naming

All graphics cards are referred to as " ATI Radeon HD" and an additional four-digit number that generally begins with a "3" (for the series). The second digit then divides the family into different market segments. The third and fourth digits then serve a subdivision in the different models. In contrast to the previous series no suffixes are used, but the performance of classification within the series or the market segment is only about the number.

Distribution:

• HD 3100/3200/3300: IGP
• HD 34xx: low-end
• HD 36xx: Mainstream
• HD 38xx: Performance
• HD 3870 X2: High- End

Model data

Notes:

• The specified clock rates are fixed or recommended by AMD. However, is the final determination of the clock rates in the hands of the respective graphics cards manufacturers. Therefore, it is quite possible that there are graphics cards models or will be having different clock speeds.
• With the stated date of the appointment of the public presentation is given, not the date of availability of the models.
• The TDP - the manufacturer may differ from the real maximum power consumption.

Performance

For each model, the following theoretical power data:

Notes:

• The above performance data for the computing power of the stream processors, the pixel fill rate, the Texelfüllrate and memory bandwidth are the theoretical maximum values. The overall performance of a graphics card depends, among other things, on how well the available resources can be exploited or utilized. In addition, there are other not listed here, factors that affect the performance.
• The computing power of the stream processors is not directly comparable with the performance of Nvidia Geforce 8 series, as they built on a different architecture, which scales differently.
