Intoduction
Just over a couple of months' ago ATI's DX10 GPU line-up was looking
threadbare, to say the least. The low-end (sub-£100) was
taken care of by the Radeon
HD 2000-series of GPUs, sure, but then jumped right up to the
Radeon HD 2900 XT, costing £250 at the time.
The Radeon
HD 3850/3870
GPUs patched up the sub-£150 market by introducing a number
of
new features which were allied decent, if not stellar, 3D performance.
ATI is of the opinion that its entire line-up should now reflect the
improvements brought by HD 3850/3870. To that end, it's releasing three distinct low-to-mid-range SKUs to
replace the Radeon HD 2000-series.
Please welcome the Radeon 3450, Radeon 3470, and Radeon 3650. Read on
to see just how they beat out the current range.
Nomenclature
The underlying architecture is similar to the upper echelons of the
Radeon HD 2000-series, which we took a look at here.
So just as the Radeon
HD 3800-series incrementally improved
upon the Radeon
2900 XT that was launched eight months previously, the Radeon
HD 3650 does the same when compared against the HD 2600 in its various
guises.
Taking it from the top, as per the models higher up in the 3K
range, the HD 3650 doesn't ship with Pro or XT suffixes. Rather, the
two models in the range are both referred to as Radeon HD 3650, and the
user will need to determine whether the main differentiating factors -
memory speed (GDDR3 or DDR 2) and size (256MiB or
512MiB) - are
present on the card of their choice. It's these factors, and these
factors alone, that define the actual Radeon HD 3650 sold by add-in
board partners.
First observations
No real surprises with the introduction of three distinctly new SKUs that bolster the Radeon HD 3000-series line-up. ATI's updates to its low-end GPUs take in much of what was new in the HD 3850/3870 range and add better display options to boot. With the introduction of these new SKUs, then, there's no compelling reason to look at HD 2400/2600 cards now, other than, perhaps, a sharp drop in price. The HD 3450/70/3650 are cheaper to produce, offer similar 3D performance, yet are more future-proof than the current range. We await to see NVIDIA's refresh for its range of sub-£50 (retail) GPUs with bated breath.
No benchmarks?
ATI, the graphics arm of AMD, in its infinite wisdom, decided that the NDA (non-disclosure agreement) lift would expire at 5am this morning. It left product sampling for the new Radeon HD 3000-series GPUs to its range of partners. Nothing wrong with that, right?The problem with having an optimistic NDA expiration date, trumping similar announcements from your competitor, has meant that partners have been unable to sample the majority of the Press in time. Indeed, we only received our Sapphire Radeon HD 3450 512MiB yesterday and still await the first Radeon HD 3650. Further complicating the issue was ATI's decision to move the NDA date for a high-end SKU (can you guess what it is?) from today until, well, later. We were informed of the move only yesterday, too, thereby tying up testing assets further.
HEXUS is in the process of obtaining samples of Radeon HD 3470 and Radeon HD 3650 GPUs. Once obtained, we shall compare the performance, both 2D and 3D, against the incumbent Radeon HD 2400/2600-series of GPUs and, of course, NVIDIA's low-to-mid-range GeForce 8-series parts.
Summary
The new GPUs from ATI bring the expected range of 3000-series benefits
on to what are, essentially, Radeon HD 2400/2600 GPUs. Given that they
will ship at or below the current pricing for the equivalent
2000-series parts, we see no reason why anyone looking for a
low-to-mid-range ATI discrete graphics card would look towards the
incumbent models.
Whether they actually offer significant value for money and just how
well they stack up against the competition from NVIDIA can only be
answered once exhaustive testing has been undertaken. Until then, it's
only fair to reserve judgment on the overall attractiveness presented
by the new SKUs.
