AMD Radeon HD 6450 Recensie | 118 Gegevens vergelijking

The AMD Radeon HD 6450, driven by the low-end "Caicos" GPU architecture, targets the sub-$60 entry-level market to provide an updated, feature-rich alternative for home theater PCs (HTPCs). It serves as a direct evolution of the older Radeon HD 5450, doubling the stream processor count to 160 shaders across two SIMD engines. The card is available in both DDR3 and GDDR5 memory configurations. The GDDR5 variant heavily boosts overall bandwidth to compensate for its narrow 64-bit memory interface, making modest gaming achievable at low settings. Its primary value lies in inheriting the modern capabilities of the Radeon HD 6000 family, such as Eyefinity multimonitor upgrades and enhanced tessellation. A major pro of the Radeon HD 6450 is its low power envelope—consuming a typical thermal design power of only 20W for DDR3 or 27W for GDDR5—eliminating the need for an external power connector. It also introduces a highly efficient UVD 3 engine that supports hardware-accelerated Blu-ray 3D decoding over HDMI 1.4a. On the flip side, a notable con is its restricted compute power compared to older, similarly priced mid-range options. For...

The 2011 AMD Radeon HD 6000 entry-level line-up (HD 6450, HD 6570, and HD 6670) offers minor, incremental upgrades over the older HD 5000 series rather than a major architectural redesign. Built on the same mature 40nm process, these budget-friendly discrete cards target the sub-£80 market to draw users away from weak integrated motherboard graphics. While the top-end HD 6670 (£75) operates essentially as a higher-clocked HD 6570 with a 20% boost in shading and texturing cores over the older HD 5670, it only translates to a modest 10% performance gain overall. Meanwhile, the ultra-low-end HD 6450 (£35) draws only 27W, allowing manufacturing partners to deploy passive, completely silent, fan-less cooling designs. The primary pros of this series lie in its heavily updated multimedia features, including the addition of the UVD 3 video-logic block, which introduces support for DisplayPort 1.2, HDMI 1.4a, and hardware acceleration for Blu-ray 3D, DivX, and Xvid codecs. Additionally, the HD 6670 expands multi-monitor Eyefinity support up to four screens. However, the major cons include the highly stagnant gaming performance, as AMD failed to transition to...

The TechPowerUp review of the Sapphire HD 6450 Passive highlights its 0 dB, fanless design, making it an ideal choice for HTPCs, along with support for native HDMI 1.4a and high-definition video acceleration. While providing decent overclocking potential and low power usage, the card is severely limited by slow DDR3 memory, which causes it to perform 46% slower at lower resolutions compared to original press samples and fall behind the NVIDIA GT 520. Consequently, the card is deemed unsuitable for 3D gaming, offering poor value for any task requiring significant graphics processing.

The ⁠Impulse Gamer review evaluates the AMD Radeon HD 6450 and HD 6670, two budget-friendly graphics cards built on 40nm architecture. Tested on a Windows 7 system with an Intel Core i5 processor and 6GB of RAM, both cards demonstrated exceptional clarity, accurate colours, and seamless multi-monitor capabilities via AMD’s EyeFinity technology. The HD 6670 targets budget-conscious gamers, achieving playable real-world performance by averaging 62 FPS in Call of Duty: Black Ops and 39 FPS in BioShock 2 at 720p with high quality settings. In contrast, the HD 6450 is strictly a multimedia and office accessory; it scored poorly in benchmarks (691 in 3DMark 11) and struggled heavily in games, plunging to an unplayable 5.5 FPS in StarCraft II at 1080p. The primary advantages of both cards are their excellent value, low power draw, DirectX 11 compatibility, and ability to support up to three independent displays flawlessly. For the HD 6670 specifically, a notable pro is its ability to handle modern games adequately if settings are lowered. However, a shared disadvantage is that both units score in the lower range...

The AMD Radeon HD 6450 review by Expert Reviews positions this entry-level graphics card as an affordable, ultra-compact component designed primarily for casual gaming and slim media center PCs. Priced at just £34 including VAT, the card features a half-height design, operates quietly, and draws all its required power directly from the PCI Express x16 slot without needing external power cables. Internally, the hardware configuration includes 160 stream processors, a 750MHz core speed, and 512MB of DDR5 memory clocked at 900MHz. In performance testing, it significantly outperforms both its predecessor (the HD 5450) and Intel's standard Sandy Bridge integrated graphics, with AMD pitching it as a highly cost-effective 3D graphics alternative when paired with a budget AMD CPU. The card has distinct pros and cons depending on the intended user setup: Pros: Highly affordable budget price of £34. No auxiliary power required from the power supply. Compact half-height and quiet design, making it highly suitable for slim home-theater PC builds. Passively cooled options are available for silent operation. Deliver playable framerates (45.4fps in Call of Duty 4 and 36.6fps in...
