We are two weeks from AMD Radeon HD 7800 Series to be released. First leaked photograps are leaking onto web. This time we have a full specification on a official AMD slide.
Specification are sligthly different than previously leaked. Mostly core clocks are different and power consumption. Radeons HD 7870 core clock is set to 1000 MHz, while Radeon HD 7850 has a core clock of 860 MHz. Both cards feature the same amount and type of memory which is 2GB of GDDR5. Radeon HD 7870 and 7850 have a bandwidth of 153.6 GB/s with a data rate up to 4.8 Gbps. Memory clock was set on both cards to 1200 MHz. Radeon HD 7870 has more stream processors (1280) than Radeon HD 7850 (1024). Also Pitcairn XT counts more texture units (80) than Pitcairn Pro (64). Computing performance of HD 7870 was measured at 2.56 TFLOPS, which is more than Radeon HD 7850 (1.76 TFLOPS). Radeon HD 7870 reaches a texture fillrate of 80 GT/s, while pixel fillrate was measured at 32 GP/s.
AMD Radeon HD 7870 required at least 175 Watts of power, while Radeon HD 7850 will consume around 130 Watts. New technology from AMD – ZeroCore – can dramatically decrease power consumption on both cards to 3 Watts.
AMD Radeon HD 7800 series are expected to be launched around 15th March.Radeon HD 7870Radeon HD 7850GPUPicairn XTPitcairn ProProcess28nm28nmEngine Clock1000 MHz860 MHzPrimitive Rate2 prim / clk2 prim / clkStream Processors12801024Compute Performance2.56 TFLOPS1.76 TFLOPSTexture Units8064Texture Fillrate80 GT/s55.0 GT/sRaster Operating Units3232Pixel Fillrate32.0 GP/s27.52 GP/sZ/Stencil128128Memory Type2 GB GDDR52 GB GDDR5Memory Clock1200 MHz1200 MHzMemory Data Rate4.8 Gbps4.8 GbpsMemory Bandwidth153.6 GB/s153.6 GB/sTypical Board Power~175 W~130 WAMD ZeroCore Power< 3 W< 3 W
PowerColor HD 7870 PCS+
Taking a different approach to HD 7870 cooling, PowerColor’s card - priced at £285 and dubbed the HD 7870 PCS+ - features a single central fan measuring 92mm in size.
It isn’t quite as eye-catching as Gigabyte’s WindForce, but the PCS+ is smarter-looking and in our estimation more elegant. The black shroud is finished in a smooth velvet-like texture, and the cooler is sized to fit the card, resulting in a length of 245mm.
Maintaining the flow of the minimalist colour scheme, PowerColor’s PCB is all-black and indistinguishable from AMD’s reference design.
Once again, a single CrossFire link is available for two-way HD 7870 configurations, and power is sourced through two six-pin PCIe connectors.
So how about the overclock? Gigabyte’s boost in out-the-box performance is limited to the Pitcairn XT core, but PowerColor opts to overclock both GPU and memory.
By default, the HD 7870 PCS+ is shipped with a core frequency of 1,100MHz (up from 1,000MHz) and a 2GB GDDR5 frame buffer clocked at an effective 4,900MHz (up from 4,800MHz).Gigabyte Amd Radeon Hd 7870
There isn’t a lot to separate the two cards in terms of price and speed, so it’s likely to be the performance of the cooler that sets them apart. While Gigabyte’s WindForce uses three fans and two heatpipes, PowerColor’s PCS+ tackles heat dissipation with a single PWM fan and three heatpipes.
How much difference can a cooler actually make? We’ll provide hard numbers later in the review, but the answer is quite a lot. One of these cards is ultra-cool but a tad loud, the other is ultra-quiet but a touch warm, but can you guess which is which?
Rounding off the last set of differences, PowerColor also takes a unique approach to HD 7870 outputs. Rockstar free agent bmx bike price. In addition to the standard array of dual-link DVI, HDMI and two Mini DisplayPorts, the PCS+ card mirrors what was typically on offer from 6000-series cards by throwing in a single-link DVI connector as well.Gigabyte Amd Radeon 7870
In summary, Gigabyte’s £290 card offers a 100MHz overclock on the core, three fans and two heatpipes. PowerColor’s £285 card offers a 100MHz overclock on the core, a 100MHz overclock on memory, one fan and three heatpipes. Let’s find out which is the better bet.
