ATI RADEON HD 5450 512MB
HD 5450 product brief.
While the HD 5450 is unlikely to debut to fervent fanfare, it's a significant
release for the HTPC crowd. As a member of the HD 5000 family, it has the ability
to bitstream Dolby TrueHD and DTS-HD Master Audio, a feature that until now,
would've required the purchase of a $100+ graphics card (or an even more expensive
sound card). Many HTPC enthusiasts have been waiting with bated breath for this
one feature alone. The card also supports DirectX 11 of course, and the Eyefinity
multi-display technology, though the reference sample we received does not as
it lacks a DisplayPort connector.
Our Radeon HD 5450 sample.
Our HD 5450 review unit from ATI doesn't look much different from any other
entry level graphics card, with a narrow, short low profile circuit board and
standard outputs. The heatsink however is rather remarkable, being large enough
to extend into the adjacent expansion slot. It's also an eye-catching blood
red, a cosmetic touch rarely seen on a reference sample.
Technical specifications according to GPU-Z.
From a technical standpoint the HD 5450 is very close to slowest card from
ATI's last generation, the HD 4350, with both having a 64-bit memory bus and
80 stream processors, though the 5450 has a higher core clock speed. The 5450
is also equipped with faster GDDR3 memory rather than the typical DDR2 used
in their entry level cards. Our sample shipped with 1.1ns Samsung GDDR3 memory
chips clocked at 900MHz, which is 100MHz higher the the reference maximum.
