i'm steve lai. nvidia has unveiled its latest chip that could transcend generative ai technology to the next level. the new processor could scale up the company's dominance in the chipmaking industry. our north american business correspondent erin delmore has the details. nvidia unveiled its new graphics processing unit at a developers conference in california on monday. it is meant to build on the success of the company �*s existing gpus which are in demand around the world. nvidia makes powerful chips that are used to develop ai technology and the blackwell is expected to allow more advanced ai models to be built. it is also expected to be a boon for the company which has ridden ai enthusiasm to the top of the market. at the developers conference in california on monday the ceo

of the company called generative ai the defining technology of our time. some of the biggest names in tech are expected to use blackwell gpus and we expect to see the technology in action later this year. bob o'donnell from technalysis research was at the event in sanjose, california. with all the anticipation built up for nvidia's latest product, he says it wasn't your typical technology conference. the atmosphere was like a rock concert. i have not seen something like this in the tech industry in quite some time. some people were making analogies to the early days of steve jobs but the buzz was in the air and the feel of the event was very much like a concert. and jensen was a rock star. he has presented many times in the past but this was clearly his moment and he was soaking it up because the company is on top of the world right now. everyone wants to know what are they going to do? they have a new blackwell gpu, the latest chip to accelerate ai and then, importantly,

not quite as sexy nor as well understood, they had software innovations that will help to make the process of companies using generative ai which use their chips easier and that will be a big dealfor them in the long run. tell us how nvidia are keeping ahead of the competition. they seem to be the market leader at the moment. one of the interesting things about blackwell, on one hand you can say it is the next generation chip and technically it is but what is interesting about what is happening with it in the world of generative ai is that many of the earlier chips that were being used for generative al was designed well before most people knew what generative al was. blackwell is arguably the first generation of chip that was designed in this gen ai era so they knew what they were doing. and there are a number of elements there that in some cases you want

4x or 5x improvements in performance versus previous generations. so they have done a number of things internally within the chip that allow them to access a bigger large language models and do twice as many calculations. and that is all by refinements within the architecture. who are their biggest rivals? can they keep pace? the biggest competitor is amd and to some degree intel but the other thing is that all major cloud providers, google has some of their own ships google has some of their own chips and so does microsoft and amazon so each of the big cloud companies have some of them but they still rely heavily on nvidia. amd is the biggest challenge and amd has been making excellent progress. the thing is the market is growing so quickly that even if nvidia loses some share they can still grow their overall business because there is just a lot

of opportunity for everybody. nvidia has also announced that it is expanding its partnerships with byd and other chinese automakers that are racing to build self—driving vehicles. byd overtook tesla last year as the world's top selling electric vehicle manufacturer. it will use nvidia's next generation of in—vehicle chips. its rivals xpeng, li auto and aion hyper gt will also use the product. evergrande group's founder has been barred from china's securities market. regulators have accused the group's flagship unit of securities fraud, failing to make timely disclosures, and inflating its earnings by around $80 billion. hui ka yan was once asia's second—richest man and in charge of one of china's biggest real estate developers. but last september, evergrande said its founder was being investigated over suspected crimes. the bank ofjapan will

wrap up its two—day policy meeting today. there's a lot of expectation from analysts that the central bank will put an end to its negative interest rates that have been put in place since early 2016. today, japan is the only nation left in the world that still has such a policy. nobuko kobayashi, partner at ey, told us how the departure from negative rates would impact companies and households in the world's fourth—largest economy. it will be a good change ifjapan does trigger the productivity gain and stimulus for the domestic economy. it will be bad if inflation is just driven by war or supply chains disruption. in that case it will run out of steam and will only offset the increase. what are the implications for consumers? you will feel the change in the short term and found multiple dimensions. the saving styles of japanese people may see the interest

rate go up on the saving account and that is good news. on the other hand people may see interests go up if they have a variable rate mortgage payment. and will this have an impact on currency? where does it leave the yen? a hike would mean the japanese yen will be stronger, theoretically speaking. that said there is still a large discrepancy between the overseas and japanese interest rates there for this exit is unlikely to impact the currency fluctuation that much. going forward, more importantly is the incremental steps that they take at the bank of japan. and at what tempo. so that is to be seen but for now the boj has been gingerly moving interest rates so we will not see big turbulence.

we will be keeping an eye on whether or not that rate increase does happen in a few hours time. the indian city of bengaluru, home to some of the biggest it companies in the country, is battling an acute water shortage after poor rainfall. ineffective water conservation has made matters worse, leading to reservoirs drying up. the bbc�*s arunoday mukharji reports on how the crisis is affecting the city known as india's �*silicon valley'. residents waiting for a basic need. water. something they should have had easy access to within their homes. now both water and people's patience are running low. drinking water atms here are in high demand. for less than a dollar people fill a can but it is a daily hassle. that glass of water first thing in the morning that so many people take for granted has become a struggle for people over here in some

parts of bengaluru. this is a daily morning routine. lining upjust to get their bottles filled. this is the main source of water, but it has failed to reach all corners of a rapidly growing city. made worse by poor rainfall, forcing sections of the city to rely completely on water tankers. this neighbourhood of 3500 residents needs 50 tankers a day. but supply now is down to half. they have to go far away to get the water and the cost escalates around twice the cost that we are paying right now. despite authorities putting a $12 cap on prices for water tankers, in some parts of the city people say they are charging double or even triple the amount. authorities say they are working on alternatives to tide over the crisis.

depending upon the water sources for other non—drinking purposes we plan to take that water to the commercial industry establishment who can do water recovery. bengaluru is the fourth largest technology hub in the world after silicon valley, boston and london. but it has come at a price. the population boom swallowing up the city's many lakes, once also a crucial source of water. we are completely reliant on the water. we need to re—architect solutions including lake water, rain water, and groundwater and treated waste water. this city of 14 million is only going to grow. and if civic infrastructure fails to keep pace, instead of a free flow of water they will be forced to count every last drop. british tech

entrepreneur mike lynch is appearing in court in the us as his trial on fraud charges gets under way. once referred to as "britain's bill gates," mr lynch is accused of overinflating the value of his software firm autonomy when he sold it and that's it for this edition of asia business report. thanks for watching.

i am julia with the catch up. our first story — only one in five nhs mental health trusts have specialists that can deal with conditions like tourettes in england and wales. that's what new research from the bbc has found. the over 300,000 people in the uk are living with the condition which causes people to make sounds and movements known as tics. big artists such as billie eilish and lewis capaldi have opened up about having it. isabelle is a journalist here at the bbc and was diagnosed at seven. my parents struggled to get the diagnosis but then

the follow—on support was not there either. in the end my mum had to homeschool me because my tics got so bad that schools just did not want to take me on. the government says it is committed to supporting people living with tourettes syndrome and other tic disorders. other stories now. nottingham forest have been docked four points for breaching the premier league's finance rules meaning the club has dropped to the relegation zone and it is likely that forrest will appeal. and banksy�*s back. on instagram he confirmed a new mural is his creation — london is his creation — with bright green paint he has made this tree look like it is blooming. and the classic banksy stencils shows someone holding a pressure hose there on the bottom left. crowds have created a buzz in the area ever since. and we will leave you with ten seconds of this ridiculously cute baby rhino. whipsnade zoo is celebrating
