sau 1 thời gian tư vấn ở các diễn đàn, mình thấy các bạn đánh giá card Radeon 6670 DDR5 rất tốt, nhưng, mình thì chỉ thấy Tân Doanh bán con Radeon 6670 DDR3 thôi //tandoanh.vn/san-pham/2322/msi-hd-6670-1gb--128-bit--ddr3.html
Vậy, mình nhờ các bạn so sánh dùm mình 2 con card này, cụ thể 6670 DDR5 mạnh hơn 6670 DDR3 tầm bao nhiu, và có nên dùng Radeon 6670 DDR3 ko, tks các pác
So với "đàn anh" GV-R797OC-3GD, card mới với thiết kế dựa trên GPU AMD Radeon HD 7970 GHz Edition có nhân xử lý đồ họa mạnh hơn, xung nhịp bộ nhớ cao hơn, mức điện năng tiêu thụ cũng tăng đáng kể.

Introduction:
Graphics card manufacturers have to develop cards to fill the needs of the masses. To generalize the groups, there are high-end, mid-range, and low-end cards. Sapphire has developed a low profile Radeon HD 6670 that should be one of the fastest low profile cards around, coming in between low- and mid-range in performance. This graphics card has been designed to be universally compatible — it supports HDMI 1.4a, Dual-Link DVI, and D-Sub VGA outputs in both low profile and standard configurations. Auxiliary power is not needed — the main requirement is just an open PCI Express x16 slot.
The Sapphire HD 6670 LP has 1GB of GDDR5 memory clocked at 4000 MHz on a 128-bit memory bus. The core is built on Taiwan Semiconductor Manufacturing Company's 40nm node and packs in 480 stream processors operating at 800 MHz core clock speed. The only major hardware requirement for the card to be used is an open PCI Express x16 slot — with VGA, DVI, and HDMI output, the card is almost universally compatible with any somewhat current system. The card supports Microsoft DirectX 11 and OpenGL 4.1, so it can handle all features of the latest Windows operating systems and applications, as well as light gaming. Streaming Blu-ray and other HD content is fully supported and office/Internet applications are accelerated too! Overall, this card should fit in well with office, media, and personal computer usage decently.
Closer Look:
The front of the box has Ruby holding a sword, dressed in purple and white garments, similar to Sapphire's color scheme. The top left has the Sapphire logo and to the right it says “Get Radeon in your system.” The front displays some of the main features of the card — 1GB GDDR5 memory with 2.8GB of HyperMemory support, full DirectX 11 support, 1080p Full HD output, AMD HD3D capable, and HDMI with 7.1 HD surround sound compatible. Flipping the box over to the back highlights some of the main features of the card at the center, while to the left is a contents list: one Sapphire HD 6670, one driver CD, and a user manual. Under this is a guide to how much HyperMemory can be associated under Windows Vista and 7. Further down is a list of many review sites that have given awards to Sapphire products [including our very own]. The sides of the box have the AMD logo and Radeon HD 6670 badges on them.
The bottom of the box specifies the product specifications and system requirements. The system requirements are somewhat generic, but include 1GB of system memory, disk drive for reading the driver disk, 400W or greater power supply, and an open PCI Express x16 slot. Everything is held within a corrugated cardboard box. Sapphire encourages consumers to recycle the packaging!
The included accessories are a case badge, driver installation CD, quick installation guide, registration pamphlet, and HyperMemory support guide. A full size bracket is also included to use this graphics card in normal systems. The VGA low profile bracket is also easily removed if the system doesn't have enough room. An antistatic bubble-wrap bag is the last line of protection for the 6670.
A great combination of performance and value, the GIGABYTE GV-R667D3-2GI graphics card offers a great solution for entry-level gamers and HD enthusiasts requiring smooth gameplay and high quality HD video playback without a hit to the wallet. It's built around 480 Stream Processors with 2GB/128-bit GDDR3 memory. A host of AMD technology such as AMD EyeSpeed, AMD HD3D, Crossfire and UVD [Unified Video Decoder] offers more than one way to boost your experience.
Performance is only a part of the story. Ultra Durable 2 design adopts the first class components, including Ferrite Core Chokes, Low RDS [on] MOSFET and Lower ESR Solid Capacitors for unmatched stability and durability during demanding condition. Custom-designed 10cm cooler efficiently cools your card while running in low noise level, helping create more comfortable environment without annoying buzzing.
