Via Technologies on Friday said its Intel platform compatible microprocessors, which were showcased by one of Tokyo, Japan’s stores, were “old stock” and the company has no plans to manufacture central processing units (CPUs) for infrastructure compatible with Intel Corp.’s.

On Thursday it was reported that Via’s C7-M chips for Intel’s socket 479m platform, which has been developed by Intel Corp., were showcased in a computer store in Tokyo, Japan. Usually, after such demonstrations products reach the retail market in the land of the rising sun. Even though the chips can reach the market this time too, the developer said that it would be the last product compatible with Intel’s infrastructure.

“The Via C7 processors that have recently appeared in Japan are older stock. Via is no longer manufacturing CPUs that are compatible with the Intel’s bus, and instead rely solely on the Via V4 bus with supporting Via C-series chipsets,” said Keith Kowal, a spokesman for Via Technologies Inc.

At least one computer components store in Tokyo, Japan, has started to demo Via C7-M 754 chips compatible with socket 479M infrastructure in Tokyo, Japan, according to a report by Akiba PC Hotline web-site. The new chip operates at 1.50GHz, sport 128KB level one cache (64KB data and 64KB instructions) as well as 128KB level two cache.

Via did not say which of its "old" chips supported socket 479m infrastructure.

Via earlier confirmed that it has license to make chipsets for Intel’s processors, including the chips for the socket 479m infrastructure. But the company has always denied to comment whether it had license to manufacture the chips compatible with Intel’s sockets or not.

Original Via’s C7-M processors, also known as Esther (also code-named C5J, Cyrix 4), incorporate 128KB L1 cache and 256KB of L2 cache, a 800MHz processor system bus as well as SSE, SSE and SSE3 multimedia instructions. The chips are capable of running at speeds of around 2GHz, the company’s earlier indications claim. The C7-M core extends the Via PadLock Hardware Security Suite to include execution (NX bit) protection, Montgomery Multiplier support for RSA encryption and secure Hash (SHA-1 and SHA-256) algorithms in addition to the Via PadLock RNG and Via PadLock ACE that are featured in the current Via C5P Nehemiah processors.
