      Opinie

      Opis producenta

      XFX HD7870 XT Tahiti LE to limitowana edycja kart graficznych opartych na zmodyfikowanym rdzeniu znanym z najmocniejszych serii AMD — HD7950 i HD7970. Wykonany w procesie technologicznym 28nm GPU Tahiti LE dysponuje procesorami strumieniowymi w ilości 1536 (seria 7870 chwali się 1280 procesorami strumieniowymi, a 7950 ma ich 1792).

      Nad kulturą pracy czuwa autorski cooler — DoubleDissipation Heatpipe.

      Rdzeń graficzny konstrukcji taktowany jest zegarem 1000 MHz, a 2 GB pamięci VRAM GDDR5 pracuje z częstotliwością 1250 MHz (efektywnie 5000 MHz). Oba elementy połączone są szyną o szerokości 256 bitów. Karta pobiera bardzo mało energii elektrycznej jak na tak wydajną konstrukcję — w spoczynku 30W (3W! przy funkcji Zero Core Power), a podczas maksymalnego obciążenia 210W.

      XFX HD7870 XT Tahiti LE wspiera w pełni wszelakie aspekty, które nowy system operacyjny, Windows 8 ma do zaoferowania. Architektura rdzenia graficznego — GCN jest już obecnie wykorzystywana przez wiele aplikacji i gier. Weźmy jako przykład Adobe Photoshop czy też WinZip — te aplikacje uzyskały wzrost wydajności o około 25% dzięki architekturze GCN i systemowi Windows 8.

      XFX HD7870 XT Tahiti LE jest zgodny ze wszystkimi najważniejszymi technologiami udostępnianymi przez AMD, takimi jak akcelerator odtwarzania UVD 3,0, AMD PowerPlay, AMD Eyefinity, przyspieszenie sprzętowe AMD APP, łączenie kart w konfigurację 2-Way CrossFire za pomocą specjalnego mostka oraz technologię AMD HD3D umożliwiającą wyświetlanie obrazu 3D w grach. Karta wspiera API DirectX 11.1, OpenGL w wersji 4.2 oraz OpenCL 1.2.

      Eyefinity 2.0
      Technologia Eyefinity™ 2.0 oferuje zupełnie nowe wsparcie dla Stereo 3D, rekonstrukcję krzywizn i nowe konfiguracje monitorów, co pozwala użytkownikowi na dobór odpowiedniej rozdzielczości. Umożliwia także przenoszenie paska zadań systemu Windows na dowolny z ekranów.

      Technologia AMD HD3D
      Technologia AMD HD3D jest oparta na zaawansowanym, otwartym ekosystemie, który w połączeniu z innymi sprzętowymi i programistycznymi technologiami firmy AMD umożliwia wyświetlanie obrazu 3D w wielu aplikacjach i środowiskach na komputerach PC.

      ZeroCore Power
      AMD wraz z wprowadzeniem kart rodziny Southern Islands zaimplementowało także technologię oszczędzania energii dla trybu «long idle». Teraz karta graficzna może wyłączyć większość swoich funkcjonalnych jednostek GPU, gdy nie są używane, pozostawiając aktywną tylko szyny PCI Express i kilka pomniejszych elementów. To w efekcie zmniejsza zużycie energii w stanie bezczynności z 15W do 3W trybie bezczynności. Pobór energii jest tak niski, że ZeroCore Power wyłącza wentylator.
      ZeroCore Power aktywne jest tylko w konfiguracji CrossFire™, gdy jedna z kart jest nieużywana.

      Technologia AMD App Acceleration
      Oparta na zestawie innowacyjnych technologii sprzętowych i programowych technologia AMD App Acceleration zapewnia szybkość i wydajność znacznie wyższą niż tradycyjne przetwarzanie grafiki i wideo.

      Digital Multi-Point Audio (DDMA)
      Technologia jest krokiem milowym związanym z dźwiękiem wyprowadzanym przez wyjścia karty graficznej. Tradycyjnie akceleratory udostępniają dźwięk przez port HDMI i audio zostaje ograniczone do jednego urządzenia: monitora, telewizora lub odbiornika. Z DDMA teraz można wysłać dźwięk do wielu urządzeń za pośrednictwem DisplayPort w połączeniu z interfejsem HDMI. Od teraz na każdym z urządzeń, do których przesyłany jest obraz i dźwięk użytkownik będzie miał możliwość usłyszenia i zobaczenia innego strumienia audio/wideo.

      Cechy:

      • unikatowa konstrukcja oparta na rdzeniu Tahiti LE
      • autorski system chłodzenia DoubleDissipation Heatpipe
      • wsparcie dla najważniejszych technologii AMD
      • wsparcie dla Windows 8
      • świetna kultura pracy
      • zgodność z PCI Express 3.0

      Introduction

      What happens if you remove a quarter of the execution processors and a third of the data bus width in the graphics core? Marriage? No, you didn’t guess, it will be HD 7870 XT. A video card that, by analogy with previous years, would be more correctly called HD 7890 or HD 7930. middle class level. Yes, the tradition has not gone anywhere, only the name has changed, but not the positioning. Then why did the manufacturer enroll his product in the ranks of HD 78xx, and not HD 79xx? The answer is very simple – the cost of the novelty is comparable to the average price of the HD 7870. Doesn’t this mean that we have a potential hit? Let’s test the hypothesis on the example of the Sapphire HD 7870 XT video card, provided for testing by our good friends, the Regard company.

      B — PCB width, excluding PCI-E pins and cooling system.
      C — height from the horizontal plane of the printed circuit board to the level of the upper surface of the cooling system.
      D — diameter of the fan/s along the outer radius.

      A1 — length of the printed circuit board, including the cooling system (if it extends beyond the printed circuit board) to the bracket for the video output ports.
      1 — width of the printed circuit board, excluding PCI-E pins, but including the measurement of the cooling system (if it goes beyond the printed circuit board).
      1 — height, taking into account the back plate (if any) / radiator mounting screws to the level of the upper surface of the cooling system. If it is lower than the height of the back plate of the video output ports, then the height is measured to the top point of the bar.

      The design of the Sapphire HD 7870 XT refers to a modified version of the HD 7870. It is worth digressing here and recall that the HD 7870 PCB concept was originally a five-phase Dr.MOS design, but over time, some problems appeared. More precisely, one very global problem that greatly affected the consumer demand of the entire HD 78xx line is a sudden black screen. After some time, many users began to complain about video cards failing, and AMD revised the design, replacing Dr. MOS to other components.

      The Sapphire model itself is a reference version of the second revision of the HD 7870. Its power section is shifted to the video ports. Instead of a pair of DVI, only one connector remained on the rear panel, in addition to it, there was a place for two Mini DisplayPort and one HDMI. But the entire upper part is given over to the removal of heated air. The set of power connectors is represented by two 6pin. From the HD 79xx, the new product got a switch and two BIOS images. Essentially, by adding the capabilities of the HD 79xx to a product with the HD 7870 design, AMD has created a funny Frankenstein.

      PCB

      There are two types of non-reference accelerators. The first is an improvement of the reference product, which is often found in ASUS, Gigabyte, MSI, Sapphire models. It is worth noting here that not always a more expensive option indicates an improved design. Therefore, without a complete disassembly, it is impossible to say whether the card is an improved version, or, conversely, saved somewhere. Moreover, the importance of the brand does not always indicate an improvement in the physical properties of the product.

      The second type is with simplified circuitry, when coils and power elements are either replaced by cheaper analogues, or the number of phases is reduced. Such options are also found among the decisions of industry leaders, but second-class brands use this method more often.

      In this case, Sapphire did not experiment, using the design recommended by AMD. So, all claims can be made only to him. Usually AMD makes cards with a significant headroom that can provide a twofold increase in power, but not this time. Even the HD 7870’s five-phase power supply would have been preferable, but savings are savings. AMD is well aware that it is easy to take and copy the HD 79 printed circuit boardxx can’t. First, she’s expensive. Secondly, the HD 7870 XT received a 256-bit memory bus instead of 384. Thirdly, the final power consumption in theory will be closer to the HD 7870 variant, and not 7950. In practice, I am almost sure that the increased frequencies (albeit with disabled memory controllers and stream processors) should not greatly affect the gluttony of the video card.

      On the right side of the Sapphire product are two power supply systems — PLL and memory. Both of them are endowed with simple PWM controllers.


      For memory, an elementary and I2C protocol-free PWM controller APW 7165 is used, in which no voltage control levers are implemented.

      Four GPU power phases lined up vertically on the left side. As befits a solution of this level, high-quality coils, capacitors and power transistors are used. So, with careful listening to the coils under different loads, I did not find any extraneous sounds. Each pair of phases works with a driver.


      The Chil 8225G PWM controller is capable of controlling five phases.


      This is a fairly advanced controller, with modern energy-saving technologies embedded in it. They allow you to turn off several phases at times of partial loads, up to the fact that only one phase remains working. Naturally, it is endowed with an extensive list of compatible protocols: I2C, SMbus, PMbus, which makes it possible not only to diagnose and monitor a large number of parameters, but also to control the voltage programmatically.


      Tahiti LT processor ~365 mm area 2 placed on PCB in week 32, 2012. It contains 4300 million transistors and is made according to the 28 nm process technology. Its silicon crystal is protected by a metal frame.


      Eight Hynix memory chips soldered on the front and labeled H5GQ2h34AFR-R0C. They are designed for frequencies up to 1500 MHz (effective frequency 6000 MHz), the bus width is 256 bits.

      The final power phase formula is 4+1+1 (GPU/MEM/PLL).


      The stock frequencies of the Sapphire HD 7870 XT are 925 MHz for the graphics core (975 MHz in Turbo mode) and 6000 MHz for the memory.

      Cooling system

      The design of the Sapphire HD 7870 XT cooling system consists of several parts. The main ones are a radiator with fans and a casing. In this case, the reinforcing side plate is not used, but there was a place for a heatsink for the power supply and memory system. And in addition to the classic parts of the CO, a couple of interesting details were discovered, but stop, let’s start in order.

      After removing the casing, the main heatsink and four heat pipes included in it — three 6 mm and one 8 mm. In its center there is a copper base, on which neat grooves are applied. By increasing the roughness, the engineers achieved a clearer spreading and penetration of thermal paste. The fins of the heat dissipator are firmly fastened together, and the distance between them is not very large. In theory, by increasing the area, we improve the efficiency of the heatsink, but let’s face it, it is necessary to cool not only the memory, but also the power system under it. Fortunately, a separate radiator is provided for these purposes.

      Its dimensions are too small for the declared energy consumption, and, in my opinion, it will be the weak link in the whole design. Another fact worsens the situation — the location of the radiator relative to the fans. It falls into the dead zone of the air flow for a good half.

      Horizontally placed memory chips are cooled through a thermal pad from the main radiator, while vertically placed memory chips are content with a separate plate. The type of its attachment to the printed circuit board is very unusual. In addition to two screws on the sides, strips of double-sided tape are glued to a large plane. And where the holes for the screws go, it is simply torn off! This is why Sapphire can actually put «Real Handmade!» on the box.

      Four radiator stands continue the set of interesting discoveries.


      They are glued with an identical double-sided tape directly on the PCB, leveling and limiting the horizontal movement of the radiator. After unscrewing the screws of its fastening, for a long time I could not understand why it does not separate. A detailed study of the entire structure took several minutes, after which the cause was found. It turned out that these four coasters are glued in both directions!

      This is what the graphics card looks like after the heatsink has been removed.

      Quite an unusual way to use adhesive tape for computer components. In my practice, I first met with household tape.

      A massive casing with a pair of fans crowns the cooling system.

      In general, I liked the cooling of Sapphire. Four amazing miniature stands, separate heatsinks for the memory and power section, a large heatsink with a quality base and neat assembly. The main problem is likely to occur in the food zone. The heat transfer area at the radiator for the declared heat dissipation is small, and the location itself cannot be called successful. However, everything will be clear only after receiving preliminary test results.
