ผมเคยบอกว่า ชิพประมวลผลเสียงของ X-Fi Xtreme Music (CA20K1)
ว่าน้องๆ Intel Pentium III นับว่าผิดพลาดอย่างมาก
ว่าจะลองดูค่าความถี่จริงๆสักที พอดูก็ถึงกับอึ้งเหมือนกัน
ไม่ใช่ค่ามันต่ำกว่าที่ผมบอก ....แต่มันสูงกว่าที่ผมบอกมากเลยครับ
มันสูงกว่าPentium 4 Extreme Edition 3.2 GHz อีกครับ
ลองดูค่ามันครับ ...(ฝรั่งก็มีมั่วบ้างพิมม์ผิดบ้างก็อย่าถือสาครับ)

X-Fi audio processor:
The X-Fi CA201K audio processor is manufactured on a 130nm process, is clocked at 400MHz and utilizes over 51 million transistors that are capable of producing over 10,000 MIPS (Million Instructions Per Second). In comparison, an AMD Athlon FX-57 is capable of producing 12,000 MIPS at 2.8GHz, and an Intel Pentium 4 Extreme Edition produces only 9,726 MIPS at 3.2GHz. The X-Fi audio processor features a SRC (Sample Rate Conversion) engine that is precise enough to be able to convert any audio resolution to any other audio resolution at near transparency with 136db SNR (Signal-to-Noise Ratio) THD+N (Total Harmonic Distortion + Noise) and digitally-matched recordings at rates from 44.1kHz to 96kHz. According to Creative's literature, the X-Fi audio processor is over 24 times more powerful than it's predecessor, the Audigy 2.

The X-Fi CA20K2 audio processor appears to be designed off the same manufacturing process as the CA201K APU, with the only major notable change being that the CA20K2 is a native PCI-E processor . . . meaning it will not have to rely on a PCIE translation chip for BUS communications, which would severelly impact audio processing latencies. Little is known of this APU at the moment, more info will be added as it surfaces.

X-Fi (audio chip)
X-Fi (for "Extreme Fidelity") is the commercial name for Creative Labs' E-MU 20K1 audio chip, later applied also to the E-MU 20K2, and the CA0106 and CA0110 chips. The chip was launched in August 2005, and ever since it has been used in a variety of audio solutions from Creative Labs, and more recently third party manufacturers, such as Korean manufacturer Auzentech and Audiotrak.
The 130 nm, 51 million transistors audio processor operates at 400 MHz and its computational power is estimated at 10,000 MIPS, which is about 24 times higher than the estimated performance of its predecessor – the Audigy processor.
A big improvement in the X-Fi DSP over the previous Audigy design, is the complete overhaul of the resampling engine on the card. The previous Audigy cards had their DSPs locked at 48 kHz/16 bit, meaning any content that didn't match this format had to be resampled on the card in hardware, which resulted in serious intermodulation distortion. For the X-Fi, Creative completely rewrote the resampling engine and dedicated more than half of the power of the DSP to the process, resulting in a very clean resample.[citation needed] Furthermore, in "Audio Creation mode" with "bit-matched playback" option, the X-Fi can work with real 44100 Hz sample rate without any kind of resampling or other signal processing.[citation needed]

จากข้อมูลที่เห็น ชิพ CA20K1 มีค่า 400 MHzความสามารถในการประมวลผลมากกว่า 10,000 MIPS
Intel Pentium 4 Extreme Edition ความสามารถในการประมวลผลเพียง 9,726 MIPS ที่ 3.2GHz
ปล. เอามาแบ่งกันดูเท่านั้นแหละ
