Naast Anand's review zullen er vandaag nog wel heel wat meer AMD Thunderbird artikelen het net op worden geschopt. Hier alvast een kleine verzameling:
"Athlon was good, but the new Athlon is even better" is the best thing to summarize AMD's new Thunderbird processor. The new integrated L2-cache is able to boost Athlon's performance to a level that's now fully able to compete against Intel's Pentium III in almost any benchmark that's not one-sidedly enhanced for Intel's ISSE-instructions only. The attractive pricing of Thunderbird will ensure the continued success of the Athlon CPU. However, those of you who expected that Thunderbird would leave Coppermine far behind may be a bit disappointed. AMD is facing quite a bit of work if Athlon is supposed to compete well against Intel's upcoming 'Willamette' processor.
Full On 3D (inclusief AMD, VIA e.a. interviews)
3DMark 2000 shows a marginal 4-6% increase depending on Software T&L and Hardware T&L modes. In the 3DMark CPU Software T&L tests, the K75 stays close to the Thunderbird but in hardware T&L CPU tests, the Thunderbird pulls ahead by 7%.
In the OpenGL-based Quake3A, the Thunderbird seems to benefit by 11-13% over the K75, which is a markedly great improvement compared to Direct3D.The K75 manages to marginally outperform the Thunderbird in 3D Winbench although the Thunderbird wins in the CPU test by 6%.
The bottom line: In limited testing, the new Athlon processors, with 256KB of full-speed on-die L2 cache, appear to offer modestly better performance than do existing Athlons with 512KB of slower, off-die L2 cache. It might not be the boost some chip fanatics hoped for, but it's there, and it won't cost you anything extra.
Once the new AMD chipset comes out that supports DDR memory and the 266Mhz (DDR 133Mhz) bus, Intel will really only be able to rely on its touted Willamette processor which isn't due out till late fall. In the mean time it looks like AMD will certainly hold the performance crown, and they don't appear to be losing any momentum from here on out.
A huge Kudos goes out to AMD for sticking to their guns and not only holding pace with Intel, but in some cases even beating them as they did by releasing the first 1Ghz chip a couple of months ago. However, all this newfound power isn't without its price, and for current Athlon owners the price of upgrading into a new CPU and motherboard might be too much. If you're in the market for an Athlon, and haven't bought one yet, then it makes all the sense in the world to grab one.
From a performance point of view the Thunderbird is a big improvement over the original 1 GHz Athlon CPU; its full speed on-die L2-cache does away with the disadvantages of the original Athlons' discrete caches. Although the Compaq platform supplied by AMD didn’t really utilize the CPU’s full potential, we’re confident that once other manufacturers introduce their Socket-A platforms we'll see a substantial increase in performance. Looking at the benchmarks we’ve run, it looks as if the Thunderbird is easily a match for Intel’s Pentium III Coppermine, even with the slow memory throughput of the Compaq's 100 MHz FSB. We will, however, not pass final judgement until we can compare CPUs head-to-head in identical setups. Nevertheless, AMD’s Thunderbird combined with VIA’s KT133 chipset looks really promising.
